Do you mean a particular falcon species or a specific plumage type (e.g., albino, leucistic, a “white morph” like some gyrfalcons)? The cause of white wings can differ depending on the species and the exact appearance (completely white, patches of white, reduced melanin, etc.).
Brief summary of the genetics and likely causes
- Albino: complete lack of melanin from tyrosinase dysfunction. Classic gene: TYR (tyrosinase). Albinos are uniformly pale with pink eyes.
- Leucism / reduced pigmentation: partial loss of pigment-producing cells or pigment, producing white patches or overall paler plumage. Candidate genes include MITF, EDNRB, KIT, PAX3, SOX10; many leucistic patterns are polygenic or developmental.
- Patterning / piebald spotting (white patches on wings): often caused by defects/variation in melanocyte migration or distribution (genes above plus others).
- Melanism or darker vs lighter morphs: genes in the melanocortin pathway such as MC1R and ASIP often control the amount of eumelanin vs pheomelanin; other pigment genes (SLC45A2, SLC24A5, OCA2) influence pigment intensity.
- Many plumage traits are complex and polygenic; regulatory mutations (enhancers) are often involved, so a single “the gene” is frequently not known for a given wild bird.
Practical note
- For many wild falcon species the precise genetic variant producing white wings has not been fully characterized. Some species (e.g., gyrfalcon) have well-known white vs dark morphs, but the specific causal mutations are not universally established or may be complex.
If you tell me the species (e.g., gyrfalcon, peregrine, kestrel) or can describe or show the bird (all white wings vs white patches; eye color; molt/age), I can give more targeted information and look up published studies.
