The 10-year migration count trends for White-tailed Hawks suggest stable populations as signaled
by the one count site in the Gulf Region that recorded an average of 2,122 individuals in Corpus
Christy, Texas. This count was statistically significantly stable during this span. Twenty-year count
trends also reflect a stable population (Gulf Region: 2
stable). Winter survey data from the Christmas Bird Count
(CBC) show increased 10-year trends within the Texas survey
area with the annual percent change in population reported
to be an increase of 3%. The White-tailed Hawk is a species
of Least Concern, designated by IUCN red list. The species is
vulnerable to removal or overgrazing of its nesting habitat
because it requires shrubs or succulent vegetation for
successful nesting. Human disturbance or persecution may
also reduce nest success.
