Se. Hayslette et al., CHANGES IN WHITE-WINGED DOVE REPRODUCTION IN SOUTHERN TEXAS, 1954-93, The Journal of wildlife management, 60(2), 1996, pp. 298-301
Factors limiting white-winged dove (Zenaida asiatica) reproduction in
the Lower Rio Grande Valley of Texas are poorly understood. We documen
ted long-term trends in egg density (eggs laid/ha), young density (hat
chlings/ha), fledgling density, egg success, and fledging success in b
rush and citrus habitats with data collected 1954-93. All density esti
mates in citrus, and fledging success in brush and citrus, showed line
ar declines (P less than or equal to 0.04) during 1954-93. Egg density
in brush did not change (P = 0.91) 1954-68, but young and fledgling d
ensities showed quadratic trends during the same period. All densities
in brush showed linear declines (P less than or equal to 0.005) from
1969 through 1993. We evaluated 6 factors hypothesized as limiting dov
e reproduction; current limiting factors may include overhunting and e
ffects of certain pesticides.
