A bird positively ID’d in the guide is worth two in the sky.

Identifying coastal birds is the subject of a free seminar July 12 at the Harlingen Public Library at 410 ’76 Drive.

The two-hour event, which begins at 6 p.m., is sponsored by the Lower Rio Grande Valley Audubon Society.

“Improving Your Birding Skills” is one of a series of birding seminars sponsored by the Audubon Society chapter, said Sue Griffin, education chair of the Audubon chapter.

Javier Gonzalez, naturalist educator at the South Padre Island Birding and Nature Center, will deliver the lecture on resident species found on the Island and along the South Texas coast.

“I’m going to focus on residents and breeding birds of South Padre Island and the coast,” Gonzalez said. “Birds that people can see when they visit the Island in the summer.”

Gonzalez said the seminar will discuss shorebirds and other species along the coast, including some of their unique behaviors and habitat which can aid in correctly identifying a species.

Included will be least terns, black skimmers, roseate spoonbills, royal terns, black-necked stilts and more, he said.

The event is free and no registration is required. Gonzalez said there is no need to bring binoculars or other birding gear,

“Just bring a notepad,” he said.
