_{Supplementary data 1: FASTA file of aligned TLR7 genes of short vs. long distance migratory birds}

A comparison of the cDNA sequences of short vs. long distance migratory birds. cDNA sequences were pulled from NCBI, alignment and organization of the FASTA file done through Aliview. Consists of species Bald Eagle(<i>Haliaeetus leucocephalus)</i>, Peregrine Falcon (<i>Falco peregrinus</i>), Whooping Crane (<i>Grus americana</i>), Gyrfalcon (<i>Falco rusticolus</i>) for long distance migratory birds. Consists of species Burrowing Owl (<i>Athene cunicularia</i>), Northern Goshawk (<i>Accipiter gentilis</i>), White rumped snowfinch (<i>Onychostruthus taczanowskii</i>), Collared Flycatcher (<i>Ficedula albicollis</i>) for short distance migratory birds.
