Corpus Christi HawkWatch Fall 2019

Since 1997, HawkWatch International has conducted full-season raptor counts at Hazel Bazemore County Park, which sits at a horseshoe bend on the southern bank of the Nueces River about 17 miles west of Corpus Christi near the town of Calallen. In 2004, the count exceeded 1 million migrants, which was the first time any site-specific count in North America outside of Mexico reached that milestone. Broad-winged Hawks typically comprise over 95% of the total count, but counts of Mississippi Kites, Turkey Vultures, and Swainson's Hawks also typically total in the thousands. The Corpus Christi HawkWatch is the only count site in North America where you have a chance of seeing Swallow-tailed Kites, White-tailed Kites, Mississippi Kites, Zone-tailed Hawks, Short-tailed Hawks, White-tailed Hawks, and Harris's Hawks.

Directions

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.
