Dan Tallman’s Chook Weblog: Widespread Teal

Inexperienced-winged Teal are discovered throughout the Northern Hemisphere. Birds within the Previous World, Widespread Teal, breed from Europe via Asia to the Aleutian Islands. New World birds, Inexperienced-winged Teal, are discovered throughout Alaska and Canada to many elements of the northern United States. The 2 populations are actually thought of to be races of the identical species. This standing might change, as a result of genetic analysis reveals that, though the races share one haplotype, they in any other case have very totally different mitochondrial DNA.

Since shifting to Washington, Erika and I’ve looked for Widespread Teal. These geese are of informal incidence alongside each coasts of North America. We have now scanned hundreds of Inexperienced-wing Teal. On 1 March 2022 we met succeeded. Widespread Teal lack a white, verticle line behind their breasts. They’ve sturdy pale traces throughout the higher sides of their faces and below their eyes. Widespread Teal heads are barely paler than these of Inexperienced-winged Teal. Maybe the white patches on the again ends of Widespread Teal are a brighter white than the yellowish spots on Inexperienced-winged Teal. The edges of the Widespread Teal are extra coarsely barred than on the American race. Our duck reveals all these discipline marks. Much less apparent is a white, horizontal stripe shaped by the scapular feathers that needs to be apparent on Widespread Teals. Word that the scapulars on our duck are white-edged, not darkish like on a Inexperienced-winged Teal. Not having this stripe obvious might point out that this chicken is a hybrid, however hybrids often present the Inexperienced-wing’s vertical facet stripe. Due to the preponderance of all the opposite discipline marks, we have now no hassle calling this particular person as a Widespread Teal.
