Birders are descending on Hazel Bazemore County Park in Calallen for Corpus Christi Hawkwatch, which began Aug. 15 and will run through Nov. 15.

Hawkwatch is the largest and most diverse raptor migration count conducted in the United States and averages more than 730,000 raptors each fall.

A "Celebration of Flight", which is a three-day festival, will be held Sept. 25-27. The celebration is scheduled during the peak of raptor migration over the Coastal Bend when daily raptor flights of more than 100,000 have been experienced.

During the festival, representatives with HawkWatch International will host morning bird walks and lectures.

Also, at 10 a.m. each Saturday at Hazel Bazemore County Park during the three-month long event, there will be lectures given about raptors, their conservation and why it is so important that migration counts, such as in Corpus Christi, continue.

Last year, some 800 avid and beginning birders participated in Hawkwatch.

Hazel Bazemore Park is one of the parks operated by the Nueces County Parks and Recreation Department. The 77.6-acre park is located on the Nueces River in Calallen, just off of Northwest Boulevard and County Road 6.
