For example, Kestrels breeding during the Rocky Mountains may possibly descend to reduce valleys in Wintertime when snow covers their large-altitude searching grounds.
We aimed to learn more about migratory phenology and routes of American Kestrels utilizing mild-level geolocators and satellite transmitters. Here, we explain the outcomes and difficulties of such monitoring attempts. Specifically, we (one) employed place details from both equally varieties of equipment to estimate migration initiation and end dates, distance, routes, and stopover websites of a small sample of individuals; (2) documented over the reliability of recovering data from geolocators and obtaining places from transmitters; and (three) monitored a subset of individuals with transmitters over the breeding period to ascertain no matter if folks had been getting rid of or damaging transmitters.
It shares a brown again and barred gray underparts Together with the more substantial species. The male has a grey head and tail like male common kestrels, but lacks the dark recognizing on the back, the black malar stripe, and has grey patches within the wings.
