The eye colour is the tell: bronze fallow has dark burgundy eyes, pale fallow bright clear red, and dun fallow bright red. Pale Fallow reduces eumelanin 90 to 95 percent in both feathers and eyes; Dun Fallow reduces feather pigment only slightly but the eyes almost completely. Dun Fallow originated in Agapornis personatus around 1985 in the USA, and its young are very weak, so breed through splits (Lovebird Compendium, pp. 484 to 497).
The quick answer
Pale Fallow and Dun Fallow are two autosomal recessive fallow mutations told apart by the body, not the eyes: both show bright red eyes. Pale Fallow reduces eumelanin roughly 90 to 95 percent in feathers and eyes alike, so the whole bird looks washed out, while Dun Fallow reduces the feathers only slightly but the eyes almost completely, giving bright red eyes on a darker, laurel-green body.
Pale Fallow and Dun Fallow are two completely separate autosomal recessive genes in Agapornis fischeri. They sit at different loci, they affect different parts of the melanin pathway, and they produce visually distinct birds. Eye colour will not separate them, because both are bright red. The fastest way to tell them apart is by body colour and overall eumelanin reduction:
Bronze Fallow = dark burgundy eyes. This is the only fallow with dark eyes, and it is the one that must never be paired to another visual Bronze Fallow.
Pale Fallow = bright clear red eyes, on a markedly pale, washed-out body.
Dun Fallow = bright red eyes, on a darker, laurel-green body. Pale Fallow and Dun Fallow are separated by body colour and overall eumelanin reduction, not by eye colour.

Pale Fallow, in detail
On any fallow, the eye tells you it is a fallow and the body tells you which one. Pale Fallow shows bright, clear red eyes set against a very pale, washed-out body, the lightest of the fallow types. Dun Fallow has bright red eyes too, so the eyes will not separate them, but its body is distinctly darker and laurel-green, more pastel or bronze-toned. If the eyes are bright red and the bird looks markedly pale overall, you are looking at Pale Fallow, not Dun Fallow. Dark burgundy eyes mean Bronze Fallow, not Pale or Dun (Van den Abeele, Lovebird Compendium, 2016).
Pale Fallow is caused by a strong reduction in eumelanin production, roughly 90 to 95 percent, at its own pf-locus. Unlike full albino mutations (Ino) which eliminate all melanin, Pale Fallow only reduces the dark eumelanin pigment, leaving the psittacine (green/yellow) pigment largely intact but making the overall plumage appear significantly paler and softer.
The face mask, normally a deep orange-red, appears lighter on Pale Fallow birds. The green body shows a visibly washed-out, mint-like quality. That extreme paleness, not the eye colour, is the diagnostic feature: the bright clear red eye simply confirms you are looking at a fallow of some kind.
Combined with Aqua, Pale Fallow produces one of the most visually spectacular Fischer's lovebirds: a bird with the turquoise body of Aqua softened by Pale Fallow's reduction to a pastel, near-white aqua-teal. These birds, Aqua Pale Fallow, are in strong demand in most markets. See: Aqua Homo × Pale Fallow: Full Pairing Breakdown →
Dun Fallow, in detail
Dun Fallow affects a different gene from Pale Fallow and produces a distinctly different appearance. Where Pale Fallow brightens and washes out the whole bird, Dun Fallow reduces the feather pigment only slightly, leaving a darker, warm laurel-green body with an earthy, faintly bronze quality compared to a normal green.
The eyes, by contrast, are almost fully depigmented, so a Dun Fallow shows bright red eyes, the same signal as a Pale Fallow. Eye colour therefore cannot be used to tell the two apart. Dark burgundy eyes point to Bronze Fallow instead. Breeders sometimes describe the Dun Fallow colouration as "fallow-green", lighter and duller than normal, but clearly darker than the pale, chalky quality of Pale Fallow.
Dun Fallow birds are in lower demand than Pale Fallow in most markets. Their combined-mutation combinations are less sought-after, though Dun Fallow × Opaline produces an interesting warm-toned visual.
Genetics of each
Pale Fallow and Dun Fallow are both autosomal recessive, but they sit at separate, independent gene loci. They are not allelic, so they do not blend into or convert into one another. A visual Pale Fallow is not automatically split for Dun Fallow, and crossing a visual Pale Fallow with a visual Dun Fallow produces chicks split for each mutation separately rather than a single combined fallow. To carry both visually, a bird must be homozygous at both loci at once (Van den Abeele, Lovebird Compendium, 2016).

Starting from scratch with a single Visual Pale Fallow bird, here is the most efficient path to a productive Pale Fallow line:
Season 1: Pair the Visual Pale Fallow with a quality Normal (ideally from a good combination line, e.g., an Aqua carrier). All offspring will be splits. Retain the best-quality splits, ideally 2 males and 2 females.
Season 2: Pair two retained splits together (Pairing 1). Expect 25% Visual, 50% split, 25% normal per clutch. Select the best Visual Pale Fallow offspring for your breeding pairs.
Season 3: Pair visual × split (Pairing 4) for 50% visual offspring per clutch. Resist the temptation to run visual × visual: fallow young are weak, and Van den Abeele's guidance is to keep breeding through splits so the chicks that hatch are strong enough to rear. By this point your line is producing reliable, consistent Pale Fallow birds.
If your splits also carry Aqua (from a deliberate combination cross in Season 1), Season 2-3 offspring begin producing Aqua Pale Fallow birds, the popular combination that is in the strongest demand.
The OGVZW position, following Dirk Van den Abeele, is blunt: "Bronze fallow, pale fallow and dun fallow are separated mutations. We always advice not to combine them, because they are all very weak." Treat that as the rule. Keep each fallow line on its own and do not set out to build a double-fallow bird.
The underlying genetics still hold: Pale Fallow and Dun Fallow sit at different, non-allelic loci, so a single bird can carry both. But a visual Pale Fallow is NOT split for Dun Fallow, and crossing a visual Pale Fallow with a visual Dun Fallow will NOT produce double fallow visuals in the first generation, it will produce offspring that are split for each, separately. Reaching a double visual takes deliberate multi-season line breeding, and the result is a bird carrying the weakness of two fallow mutations at once. That is why the advice is not to attempt it.
Combined with Other Mutations
Dun Fallow is defined by the same red-eyed signature as Pale Fallow but paired with a darker, pastel or bronze-like body rather than a pale washed-out one. That body tone is the tell that separates the two fallows once the eyes confirm a fallow at all. Because Dun Fallow occupies its own locus, it combines with other mutations independently of Pale Fallow, and the two never merge into a single intermediate fallow no matter how they are paired (Van den Abeele, Lovebird Compendium, 2016).
Both Pale Fallow and Dun Fallow are autosomal recessive, so each combines with one bl-locus base per bird (Green wild-type, Blue, Aqua, Parblue or Yellow Face, which are all alleles of the same blue locus and therefore mutually exclusive) plus genuinely independent genes such as Dilute, Opaline, Cinnamon, Pied and Dark Factor. Neither fallow has dominant alleles or incomplete dominance, so the genetics of combining them are straightforward, the challenge is the number of generations required to build double-split birds and then produce visual combined offspring.
Aqua Pale Fallow, the turquoise pastel
The single most sought-after Pale Fallow combination in the current South Asian market. Aqua Pale Fallow birds show the turquoise body shift of Aqua alongside the melanin softening of Pale Fallow, producing a luminous pastel teal with the bright clear red eyes that confirm a fallow, on the markedly pale body that confirms Pale Fallow. On an Aqua Homo (homozygous Aqua) base, the turquoise is deeper even before Pale Fallow softening, producing the "Aqua Homo Pale Fallow" combination that sits at the very top of the Fischer's lovebird market. Building this combination requires a minimum of two seasons of split management from starting materials. For the full pairing breakdown, see the dedicated Aqua Homo × Pale Fallow pairing guide.
Opaline Pale Fallow
Because Opaline is sex-linked, combining it with Pale Fallow (AR) creates an auto-sex opportunity. A visual Opaline male that is also split for Pale Fallow paired with a visual Pale Fallow female will produce daughters that are either Opaline visual (confirmed female) or normal-looking (could be Pale Fallow split female). The Opaline Pale Fallow female, showing both Opaline plumage redistribution and the brighter softened colours of Pale Fallow, is one of the more sought-after compound birds in this group.
Pale Fallow Cinnamon
Both Pale Fallow and Cinnamon reduce melanin expression, but through different mechanisms (Pale Fallow through a 90 to 95 percent eumelanin reduction at its own pf-locus, Cinnamon via the TRP1 gene). Their visual combination produces a bird with significantly reduced melanin on two fronts, resulting in an exceptionally light, warm-toned plumage with the bright clear red Pale Fallow eye. This is a niche combination, less widely dominant than the Aqua or Opaline combinations, but appreciated by collectors who breed specifically for melanin-reduction birds.
Dun Fallow combinations
Dun Fallow attracts significantly less breeder demand than Pale Fallow in most regions, which reflects both its less striking visual appearance and the widespread perception that it is a "lesser" fallow type. Dun Fallow Aqua does exist and produces a warm-toned earthy turquoise bird with bright red eyes, interesting to specialist breeders but not a widely requested combination. Dun Fallow Opaline is similarly a niche combination. The most productive use of Dun Fallow birds is in programs that are trying to identify and eventually separate it from suspected Pale Fallow stock, a line-cleaning exercise rather than a primary breeding goal.
Model Fallow pairings and combinations
The calculator handles Pale Fallow and Dun Fallow as separate mutation slots, combine with Aqua, Opaline, or any other traitIdentifying chicks at hatch
Both Pale Fallow and Dun Fallow chicks can be spotted at hatch by their red eyes, which is how you know a fallow is in the nest at all. What the eye will not tell you is which fallow. Pale Fallow and Dun Fallow chicks both show bright red eyes from the start, and neither darkens into burgundy as it matures. A chick whose eyes read dark burgundy is a Bronze Fallow, not a Pale or Dun.
To separate Pale from Dun, wait for the down and then the first feathers and read the body. Pale Fallow chicks feather in strikingly pale and washed out; Dun Fallow chicks feather in noticeably darker, a laurel-green with a warm earthy cast. By 3 to 4 weeks the contrast is usually obvious. When in doubt, wait until the bird is fully fledged and compare it side by side against a known visual of each type.
The Critical Distinction: Pale Fallow vs Bronze Fallow
Many beginning Fischer's lovebird breeders confuse three fallow-type mutations: Pale Fallow, Dun Fallow, and Bronze Fallow. This confusion has serious consequences for Bronze Fallow, and the distinction must be clearly understood before attempting any fallow breeding programme.
None of the three fallows is a robust mutation. All three produce weak young, Pale Fallow and Dun Fallow included, and Dun Fallow chicks in particular are noted as very weak in the Lovebird Compendium. Van den Abeele's guidance for every fallow is the same: breed through splits. Pair visual × split, or split × split, rather than visual × visual, so that the chicks in the nest are not carrying a double dose of a fragile mutation. You give up some visual yield per clutch and you get back chicks that fledge. Never treat Pale Fallow or Dun Fallow as a mutation you can pair carelessly just because it is not lethal.
Bronze Fallow is more dangerous still. The Lovebird Compendium by Dirk Van den Abeele (2016) documents a critical finding: pairing two visual Bronze Fallows together produces near-total chick mortality, close to 100% loss. The mechanism behind this is not established. What is established is the outcome, so treat it as an absolute rule rather than a risk to be managed. To maintain Bronze Fallow in a breeding programme, always pair a visual Bronze Fallow to a normal or split partner. The resulting split offspring rear normally.
If you are sourcing birds labelled as "Pale Fallow" and you suspect they may actually be Bronze Fallow, the eye colour is your first diagnostic, and here it genuinely works. Pale Fallow = bright clear red. Dun Fallow = bright red. Bronze Fallow = dark burgundy, visibly deeper than either, often with a lighter iris ring in good light. A dark burgundy eye is the one eye colour that identifies a specific fallow on sight. When in doubt, do not pair two birds from uncertain fallow stock with each other until you have confirmed the mutation type from a trusted breeder or via DNA testing.
History and Origin
Both Pale Fallow and Dun Fallow are documented as autosomal recessive mutations in Agapornis fischeri in the Lovebird Compendium by Dirk Van den Abeele (2016). The Compendium documents each mutation's molecular basis, eye colour characteristics, and breeding outcomes from systematic crossing trials. Pale Fallow is identified as a strong eumelanin reduction, roughly 90 to 95 percent, at its own pf-locus, distinct from the full melanin elimination of Ino mutations. Dun Fallow operates through a different locus, which is why it produces a different visual result despite the superficially similar category name: it takes the eyes down almost completely while barely touching the feathers, so the body stays dark.
In South Asian aviculture, Pale Fallow has become significantly more sought-after than Dun Fallow over the past decade, largely driven by strong demand for Aqua Pale Fallow and Aqua Homo Pale Fallow combinations. This demand has led breeders to concentrate their efforts on established Pale Fallow lines while Dun Fallow has remained more of a specialist or educational mutation in regional collections.
Sourcing Genuine Pale Fallow: How to Avoid Mislabelled Stock
Pale Fallow is one of the most commonly mislabelled mutations in the South Asian Fischer's lovebird hobby. The consequences of taking in Dun Fallow labelled as Pale Fallow, or Bronze Fallow labelled as Pale Fallow, range from wasted seasons to, in the case of Bronze Fallow, genuine chick mortality. Here is a practical guide to sourcing genuine Pale Fallow stock.
Request photographs under natural light
Always ask for photographs taken outdoors in natural daylight, not under artificial lighting. Pale Fallow's washed-out plumage, and the exact shade of the eye that separates a bright red fallow from a dark burgundy Bronze Fallow, are most reliably assessed under natural light. A source who cannot or will not provide outdoor photographs should be treated with caution. Request both a close-up of the eye and a full-body shot showing the plumage tone.
Request parent pedigree
A genuine Pale Fallow visual bird should have at least one Pale Fallow visual parent (or two documented split parents). Ask the source breeder: "What are the parents of this bird?" If both parents appear normal green and the source cannot explain the Pale Fallow genetics from the pedigree, the mutation status is unconfirmed. A split-confirmed pedigree is the minimum acceptable documentation for a sought-after Pale Fallow bird.
Compare side by side when possible
If you can visit the source aviary, request to see the Pale Fallow bird next to a normal green Fischer's lovebird of similar age. The contrast in plumage tone should be immediately visible: the Pale Fallow bird is noticeably lighter, softer, and chalky-looking. The eye contrast against the normal bird is also clear, a normal dark iris versus the bright clear red of a fallow. Birds that look "slightly lighter than normal but not dramatically so" while still showing bright red eyes are most likely Dun Fallow, or may have mislabelled parentage.
Pale Fallow Line Health and Inbreeding Considerations
Established Pale Fallow lines in Bangladesh and Pakistan often come from relatively small founder populations, which means coefficient of inbreeding (COI) can be elevated in birds from single-source lines. High inbreeding levels in Fischer's lovebirds manifest as reduced fertility, smaller clutch sizes, weaker chick survival, and feather quality issues. These problems are not unique to Pale Fallow, they affect any tight line, but they are more commonly seen in rare mutation lines where breeders have been pairing within a limited gene pool for multiple generations.
Best practice for maintaining Pale Fallow line health: every 2-3 generations, introduce a high-quality unrelated normal green Fischer's lovebird into the Pale Fallow line (Pairing 2: Visual Pale Fallow × Normal). The resulting splits will be confirmed Pale Fallow carriers. This outcross introduces new genetic diversity while maintaining the Pale Fallow gene in the programme. The one-generation trade-off (a season of all-split offspring) is justified by the improved vigour, fertility, and chick survival in subsequent generations.
How to Confirm Your Fallow Mutation Type with a Test Pairing
If you have acquired a bird with red eyes labelled as "Pale Fallow" and you are not certain it is genuine Pale Fallow rather than Dun Fallow, a test pairing can resolve the question within one generation.
Pair the uncertain bird to a confirmed Pale Fallow visual of known pedigree, and read the chicks. If any red-eyed fallow chicks appear in the nest, the uncertain bird carries Pale Fallow, because a red-eyed chick can only result if both parents contributed a Pale Fallow allele. If every chick hatches as a normal green bird, the uncertain bird does not carry Pale Fallow at all, and Dun Fallow becomes the likely explanation for its own red eyes.
The logic works because Pale Fallow and Dun Fallow sit at separate, non-allelic loci. A visual Dun Fallow paired to a visual Pale Fallow produces zero visuals of either mutation in the first generation, only double-split normals. So an all-normal nest is a real result, not a failed test. Note that this test is itself a fallow pairing, so keep the clutch small and rear it carefully.
This test pairing approach is slower than DNA testing but requires no external laboratory and provides real-world breeding information simultaneously. Run the test pair for at least two clutches to accumulate enough offspring for a reliable assessment.
Using the Calculator for Fallow Pairings
The Lovebird Genetics Calculator treats Pale Fallow and Dun Fallow as two completely separate mutation slots. When entering a pairing, you can select Pale Fallow status independently from Dun Fallow status, this reflects the biological reality that they are at different gene loci and inherit independently of each other. A bird can be split for Pale Fallow without being split for Dun Fallow, and vice versa.
For single-fallow pairings (Pale Fallow visual × Pale Fallow split, for example), the calculator provides exact offspring percentages including the distinction between visual, split, and non-carrier offspring, all at the correct Mendelian ratios. For combination pairings involving Pale Fallow with Aqua, Opaline, or Yellow Face, the calculator handles the multi-mutation inheritance across all three traits simultaneously. This is the most reliable way to plan a Pale Fallow combination line, particularly when you are managing double-split birds from an earlier cross and need to know the exact probability of producing combined visual offspring in the next season.
The Aqua Homo × Pale Fallow pairing described in this article is documented in full detail, with exact Gen 1 and Gen 2 offspring breakdowns, in the dedicated Aqua Homo × Pale Fallow pairing guide.

Breeders usually describe a pairing as cock × hen. Below is every common Pale Fallow pairing written that way, with the exact percentages this calculator produces.
What do you get from a Pale Fallow cock x Pale Fallow hen?
Every chick is a visual Pale Fallow, cocks and hens alike. Because Pale Fallow is autosomal recessive, sex plays no part in the outcome.
| Chicks | Outcome |

| All chicks | 100% visual Pale Fallow |
What do you get from a Pale Fallow cock x normal hen?
No visual chicks appear in this generation. Every chick is a normal-looking bird carrying one hidden copy, written as normal / Pale Fallow.
| Chicks | Outcome |
|---|---|
| All chicks | 100% split (normal / Pale Fallow) |
What do you get from a split Pale Fallow cock x split Pale Fallow hen?
One quarter of the chicks are visual Pale Fallow. Half are splits and one quarter carry nothing, and the splits and pure normals look identical.

Frequently asked questions
What is the difference between Pale Fallow and Dun Fallow in lovebirds?
Pale Fallow strips roughly 90 to 95 percent of eumelanin from feathers and eyes alike, giving bright clear red eyes on a washed-out, very light body. Dun Fallow takes the eyes down almost completely but barely touches the feathers, so it also shows bright red eyes, on a distinctly darker laurel-green body. They are two separate genes at different loci, both autosomal recessive, and the body is what tells them apart.
How do you tell Pale Fallow from Dun Fallow by eye colour?
You cannot. Both Pale Fallow and Dun Fallow have bright red eyes, so the eye only confirms that the bird is a fallow. Read the body instead: Pale Fallow is markedly pale and washed out, Dun Fallow stays darker and laurel-green. Dark burgundy eyes are the signature of Bronze Fallow, which must never be paired to another visual Bronze Fallow.
Can Pale Fallow and Dun Fallow be combined in the same bird?
Genetically yes, because they sit at separate non-allelic loci, so one bird can be homozygous for both. In practice, do not do it. The OGVZW position, following Dirk Van den Abeele, is that bronze fallow, pale fallow and dun fallow are separated mutations and breeders are always advised not to combine them, because they are all very weak. Stacking two fallow mutations compounds that weakness. Keep the lines separate and breed through splits, visual to split or split to split, rather than visual to visual.
Which is more sought-after, Pale Fallow or Dun Fallow?
Pale Fallow generally is in stronger demand, especially in combination with Aqua or Opaline. Aqua Pale Fallow birds are among the most sought-after Fischer's mutations. Dun Fallow combinations are less sought-after in most markets.
Are Pale Fallow and Dun Fallow autosomal recessive?
Yes. Both Pale Fallow and Dun Fallow are autosomal recessive in Agapornis fischeri. Both males and females can be splits. Standard 25% visual / 50% split / 25% normal ratios apply for split × split pairings. All three fallow mutations produce weak young, so Van den Abeele advises breeding through splits, visual to split or split to split, rather than visual to visual.
How many seasons does it take to produce Aqua Pale Fallow birds?
Starting from a Pale Fallow visual and an Aqua carrier: Season 1 produces splits for Pale Fallow (some also split for Aqua). Season 2 pairs of split × split begin producing birds split for both. Season 3 can yield Aqua Pale Fallow visuals if you carry both genes in the same birds. With careful breeding record keeping and selective pairing, 3 seasons from separate mutation lines to double-visual combination birds is achievable. The calculator helps model which crosses produce which combinations.
What does a split Pale Fallow lovebird look like?
A split Pale Fallow looks completely normal, green plumage, normal dark eyes, no pale or washed-out features. There is no visual difference between a split Pale Fallow bird and a pure normal bird. The only way to confirm split status is through test pairings (pair with a visual Pale Fallow and look for bright red-eyed offspring) or DNA testing.
Can a bird be both Pale Fallow and Lutino?
Yes, in theory, both mutations are autosomal recessive and carried on different gene loci. A bird homozygous for both Pale Fallow and Ino would express both, though the Ino mutation's complete melanin removal would likely dominate the visual appearance. Such a double-mutation bird would be extremely rare and would require deliberate line breeding to produce.
