Aransas National Wildlife Refuge Professional Review and Guide
"Most of the 115,000-acre refuge is situated on the Blackjack Peninsula, between San Antonio and Mesquite bays on the east and St. Charles Bay on the west; a portion of the refuge is located on nearby Matagorda Island.
The refuge is the principal wintering ground for the endangered Whooping Crane (properly pronounced “hooping”), which arrives in mid-October, after a 2,500-mile flight from its northern nesting grounds in Canada’s Wood Buffalo National Park. Winter flocks currently number about 150 birds.
This guide provides detailed information on birding strategies for this specific location, the specialty birds and other key birds you might see, directions to each birding spot, a detailed map, and helpful general information."
