Blackpoll Warblers (Setophaga striata) breed across Canada and the northern United States and fly across the Atlantic Ocean to South America in fall. Blackpoll Warblers take an incredible migratory journey each fall. Abstract. For the blackpoll warbler, such a feat is called their fall migration. Their ability to withstand the low levels of oxygen available at such altitudes, the blood of blackpoll warblers is characterized by two specialized adaptations. clicking on the image below will get you a larger version, the shot above is from a shot similar to the one below. Blackpoll Warblers are one of the species for which the term “confusing fall warbler” was made. I found the warbler in our bird guide (Birds of Ecuador) so the Blackpoll Warbler flies all the way to Ecuador. Every autumn our coastal woodlands become flooded with small songbirds migrating south from their breeding habitat throughout New England and Canada. Go check it out!

Barely half an ounce (12 grams), these tiny birds fly from northeastern Canada to South America every fall. Canada has taken steps to protect large areas of its boreal forest, preserving millions of acres of habitat for the blackpoll and other species dependent on these lands, including Canada Warbler, Swainson's Thrush, and Rusty Blackbird. Everyone loves seeing all the beautiful warblers in their breeding colors in the spring but, seeing them in the fall can be just as much fun. The 2014 State of the Birds Report lists the Blackpoll Warbler as a common bird in steep decline. Just the thought that the little five-and-a-half inch bird had already migrated down from the boreal forest of Canada or perhaps one of the mountain ranges of the northeastern United States was mid-blowing enough considering the bird was still in an egg in June. The close up of the bird’s mantle feathers is really cool and I love the last “goodbye” wave shot. Its next step, once it puts on a lot of weight for energy, is to launch itself southeast out over the Atlantic until it hits prevailing winds that will be at its back as it curves to the southwest into northern South America. Blackpoll warbler migration is monitored through the park's Critical Connections program, which uses tiny geolocator tracking devises to learn more about species migration paths. Blackpoll warblers forage by gleaning insects and other arthropods from foliage and twigs and by hawking and hovering maneuvers. The oxygen-carrying capacity of the blood is enhanced by a high concentration of red blood cells and secondly, instead of one form of hemoglobin in the red blood cells as is typical in non-migrants, they possess two forms of hemoglobin which differ in their oxygen carrying and releasing capacities. #birdstagra, First Fall Blackpoll Warbler Dendroica striata, Best Bird of the Weekend (Third of November 2020). But I think I’ll go one calling warblers ‘pretty little birds’. The other amazing thing about Blackpoll Warblers is the way they change their physiology for the migration and that they fly the journey at very high altitudes where there is less oxygen. Fall warblers can be very confusing especially when you see species that look so similar such as Blackpoll and Bay-breasted. @Renato: We’ll just have to find other boreal migrants.

Blackpoll Warblers are one of the species for which the term “confusing fall warbler” was made. Blackpoll Warblers (Setophaga striata) breed across Canada and the northern United States and fly across the Atlantic Ocean to South America in fall.

Gorgeous shots of this amazing bird Corey! The dual hemoglobin adaptation explains how this bird can survive in such extreme conditions, but here in (Ecuador) it can only be found on the eastern jungle of Ecuador, the Amazon.

The same day that I got great looks at a cooperative Magnolia Warbler I also managed to spend some time studying and digiscoping a very confiding juvenile Blackpoll Warbler in the same general area. Beautiful photography! Blackpoll Warblers are one of the species for which the term “confusing fall warbler” was made. A close examination will reveal the streaking on the back that distinguishes Dendorica striata from the similar Pine Warbler, and faint streaking on the underparts, white undertail coverts, and yellow or orangeish feet and legs that rule out Bay-breasted Warbler. We have a fountain, bird bath, and bird feeders in our back yard. Blackpoll warbler migration is monitored through the park's Critical Connections program, which uses tiny geolocator tracking devises to learn more about species migration paths.
