Table 3.

Number of putatively classical and non-classical MHC-I alleles in three species within the order Charadriiformes. Range of loci and number of alleles per individual (given in brackets), within a sample of 84 Icelandic black-tailed godwits (Limosa limosa islandica) and eight red knots (Calidris canutus). For the red-billed gulls (Larus scopulinus), individual information regarding number of alleles was not available and instead information refers to the total number of loci identified across a sample of 470 individuals

Species	Classical alleles				Non-classical alleles
	Total	Short	Long	Minor
Black-tailed godwita	1–4 (2–7)	0–2 (0–3)	1–3 (1–6)	0	0
Red knotb	2–4 (3–8)	0–2 (0–3)	1–3 (2–5)	0	1–2 (2–4)c
Red-billed gulld	2	0	1	1	2
