Species in Decline

I had a great time photographing Band-tailed Pigeons (P.f. monilis) in my backyard this morning. I have nowhere near the numbers of them that I used to have visiting my bird feeders. Five or six years ago I would have flocks of twenty or more. Now flocks are typically less than a dozen. In fact this morning there were only six or so. At present the population is still considered to be a species of "Least Concern" even though they have been steadily dropping in population since 1945. Recently a new pathogen (Trichomonas stableri) has been found by scientists from UC Davis looking into major die-offs of pigeons native to North America. The pathogen creates nasty lesions that can block the esophagus. This prevents the birds from eating or drinking often leading to suffocation. Hopefully a way can be found to stop this disease so that future generations of people can enjoy seeing this bird in the wild. God bless, chris All images created with a Canon 7D and a Canon 100-400 IS lens. Camera settings used were. AV mode, ISO 800 at F 5.6. Shutter speeds varied. Camera and lens were supported with a Manfrotto 190XPROB tripod with a Bogen 3055 ballhead.
