Hi Ellen et al.,

There are two subspecies of Blue Jays that occur in Florida. One of these (cristata) is a permenent resident, but the other (bromia) is highly migratory, with flocks occasionally numbering in the hundreds of individuals.

The migratory subspecies should be most common during winter, so if your Blue Jays seem to be disappearing now, then migration is not the cause.

West Nile Virus (WNV) has hit corvids very hard in other areas of the U.S., but there is little evidence that WNV is having any effect in Florida -- perhaps because our birds may already be resistent to mosquito-borne viruses. To my knowledge, nobody has noticed reduced corvid numbers in Florida in the past several years, so WNV probably is also not the cause of the disappearance you have noticed.

Best regards,
