What specific geographic features define the core winter haven for the AWBP at Aransas NWR?
Answer
The tidal flats of San Antonio Bay and Hynes Bay
The wintering location for the entire Aransas-Wood Buffalo Population is highly localized and defined by specific estuarine conditions necessary for survival during cold weather. This single destination is the Aransas National Wildlife Refuge on the Texas Gulf Coast. Within this refuge, the cranes specifically utilize the tidal flats of two distinct adjacent water bodies: San Antonio Bay and Hynes Bay. These areas provide the necessary saline and brackish water estuaries that remain suitable for the cranes when northern environments become inhospitable, making these two bays the anchors of the migratory population's winter ecology.
