For Jim Watson and Mark Vekasy of the WDFW, bird watching extends beyond leisure. It's a vital task that bridges the gap between fascination and conservation. As revealed in the Washington Department of Fish and Wildlife blog, their meticulous tracking of ferruginous hawks, including the radio-tagging of one named hawk 264292, helps unravel the mysteries of avian migration and aids in boosting the population of these endangered birds.
Earlier this spring, Vekasy and Watson banded three sibling ferruginous hawks, with hawk 264292 being fitted with a light transmitter that charts her journey, "Most recently, we banded three sibling nestling hawks in spring 2024 as part of the study, and we’ve radio tagged one as well," Vekasy said via WDFW. Despite the natural inclination for such predators to roam free, the decimation of their native habitats, partly due to agricultural expansions, threatens their survival and necessitates such studies.
The 30-gram transmitter, which allows full movement for the hawk, has reported hawk 264292's notable displacement from her initial territory into the expanse of southeastern Washington, into Canada, and subsequently to Texas. It's a migration pattern in line with the species's behavioral norms but one that demands scrutiny to ensure the subsistence of the hawks.
Hawk 264292's detour to Nebraska suggests the trials she faced during her southward migration. "Much of the landscape that this species historically inhabited has been converted to agricultural uses or other human development, impacting nest sites," explained Vekasy through WDFW, indicating the importance of such data in comprehending and alleviating the birds’ challenges. According to Vekasy, predation, starvation, and wind turbine collisions are among the threats these migrants endure.
