Corpus Christi HawkWatch Fall 2023

Each fall since 1997, HawkWatch International crews count migrating raptors at Hazel Bazemore County Park, which sits at a horseshoe bend on the southern bank of the Nueces River 17 miles west of Corpus Christi near the town of Calallen. In 2004, the count exceeded 1 million migrants--the first time any count in North America outside of Mexico reached that milestone. Broad-winged Hawks comprise over 95% of the total count, but we also count impressive numbers of Mississippi Kites, Turkey Vultures, and Swainson's Hawks. The Corpus Christi HawkWatch is the only count site in North America where there is a good chance of seeing Swallow-tailed Kites, White-tailed Kites, Mississippi Kites, Zone-tailed Hawks, Short-tailed Hawks, White-tailed Hawks, and Harris's Hawks.


To find Hazel Bazemore County Park take FM624 west from SH77 for about 1 mile. Take a right onto County Road 69 at the stop light (look for the park sign), which takes you to the park. To go to the HawkWatch site, go in the park entrance, make a left as soon as you get across the speed bump, and follow the winding road to the crest of the hill (past the restrooms, a covered picnic pavilion and around the next bend). We operate daily 9am-5pm, August 1-November 15. All activities are weather dependent and we do not conduct migration counts in inclement weather (heavy rain).

HawkWatch International

The mission of HawkWatch International is to conserve our environment through education, long-term monitoring, and scientific research on raptors as indicators of ecosystem health.
