title: Lead concentrations of white-winged doves, Zenaida asiatica L., collected in the Lower Rio Grande Valley of Texas, USA.
abstract: White-winged dove (Zenaida asiatica L.) exposure to environmentally accessible lead is a management concern. Detectable concentrations of lead were found in 142 (66%) of 214 white-winged doves collected in 2002 and 2003 at two wildlife management units in South Texas. Mean +/- SD lead concentration was 0.70 +/- 1.10 microg/g dry weight and ranged from ND to 11.01 microg/g dw. Lead concentrations were significantly lower in the 2002 samples, but similar between management units, age, and gender. White-winged doves in South Texas are being exposed to lead in the environment with some reaching subclinical to toxic levels.
