Ring-billed Gull

I took this photo of a passing Ring-billed Gull last spring near Dallas, Texas. Unbelievably these gulls were almost eradicated by human persecution and habitat destruction between 1850 and 1920. Populations have rebounded.  By 1990, perhaps four million Ring-bills were to be found in North America.  Ten years later, this number had increased by 250% (Pollet et al, 2012). The species is still often considered a pest, for example as they swarm around garbage dumps or soil cars in parking lots, but current efforts to control populations have not been very successful.

Ring-billed Gulls, in any event, are opportunistic feeders. When they are not consuming human trash, they eat grain, a wide variety of insects, earthworms, fish, and even small rodents. I have previously blogged about this gull.
