I checked out a Purple Martin Party tonight – a spectator event coordinated by the Travis Audubon Society. Every Friday and Saturday night in July, from 8-9:30pm, people gather on the lawn outside the Texas Land & Cattle restaurant to watch tens of thousands of purple martins roost at sunset. These guys are done nesting and breeding and are on their way south to complete the annual migration cycle of life. They tell me that by the end of the month there may be hundreds of thousands of them.
How can one possibly photograph this event? Here is one shot I took, a small portion of the overall scene. Can you count them?
