Whereas it has lengthy been identified that many songbirds full huge migrations from the temperate zones to the tropics every year, surprisingly few species have been tracked alongside their total journey throughout the hemisphere to particular nonbreeding areas. Provided that occasions on the wintering grounds and alongside migration can have a big affect on birds that breed in North America, the necessity for understanding the complete annual cycle of migratory species has by no means been higher.
Enter the Kentucky Warbler, a putting yellow and black ground-dwelling forest fowl of southeastern North America. In Nebraska, this species reaches its northwestern vary restrict, breeding solely within the largest tracts of oak-woodlands on the excessive southeast nook of the state. Little is thought about this species on the fringe of its vary, and no particular person of this species has ever been tracked alongside its migration or to its wintering grounds. Populations of Kentucky Warblers have been in relative decline because the finish of final century, and it stays unclear if situations through the breeding season or the nonbreeding season are difficult the restoration of this unimaginable warbler. Learning the migratory routes and non-breeding grounds of birds in our area not solely establishes a connection between the Nice Plains and tropical ecosystems, however this additionally helps determine potential conservation alternatives past our borders.
In 2025, biologists from Audubon Nice Plains and the Nebraska Recreation and Parks Fee initiated a challenge monitoring Kentucky Warblers to find their migration routes and set up the place birds breeding at vary periphery spend the nonbreeding season. Researchers deployed light-level geolocators to trace these small birds over the course of a yr. This know-how has been used throughout many species of warblers because the mid-2010s, and was not too long ago used to find the distinctive migrations, wintering grounds and excessive survival of Ovenbirds breeding within the northwestern areas of Nebraska.
In 2026, two Kentucky Warblers tagged within the earlier yr have been recaptured on their breeding grounds and knowledge from one geolocator was recovered. Early evaluation on this tag factors to a South American wintering web site, which might imply Kentucky Warblers within the Nice Plains full two 3,000+ mile journeys every year between breeding and wintering places. Hopefully a couple of extra geolocators could be recovered and extra knowledge processing can reveal much more about these superb birds as this challenge continues into 2027.
