Nitrogen Excretion by Turkey Vultures
The Condor, 1980-The proportions of nitrogen (N), as urate-N (76.1%), NH3-N (16.4%), and urea-N (7.5%) in the urine of fasted Turkey Vultures, are similar to those found in the urine of domestic chickens and ducks, the only other birds for which comparable data are available. Vultures show an adaptive increase in the percentage of urinary N excreted as urate (up to 86.

Flight Feather Molt of Turkey Vultures
The Wilson Journal of Ornithology, 2010Abstract We document the molt sequence of flight feathers in Turkey Vultures (Cathartes aura) based on studies of captive and wild birds, and examination of museum specimens. We found an unusual pattern of primary replacement, which appears to be a modified form of Staffelmauser, or stepwise wing molt.

Noteworthy Observations of Foraging Turkey Vultures
The Wilson Journal of Ornithology, 2009Abstract We present two noteworthy observations of foraging Turkey Vultures (Cathartes aura), including consumption of a marine toad (Bufo marinus) and a live juvenile cotton rat (Sigmodon hispidus). To our knowledge, these observations are the first reports of any North American vulture consuming B.

Hematocrit and Protein Concentration of Black Vulture and Turkey Vulture Blood
The Condor, 1988Blood protein concentration and hematocrit (packed cell volume) values are easily obtained and can be useful in determining the health of trapped or captive birds (Hunter and Powers 1980, Duke and Redig 1984). However, if these parameters are to be useful, there must be baseline data for comparison.

Serum proteins of wild turkey vultures (Cathartes aura)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1983We separated and identified the major serum proteins of turkey vultures (Cathartes aura): albumin, HDL, LDL, IgG and M, transferrin, alpha 2M and putatively, IgA, ceruloplasmin and fibronectin. Turkey vulture HDL and LDL had similar electrophorectic mobility and solution properties as those from gallinaceous birds.
