This is the time of the year when any bird flashing different plumage warrants attention. Mixed in with the vagrants is the ever-challenging Blackpoll.
This is one species of warblers that presents with many different plumages as we see the bird go through molt as well as immature birds and males and females.
Yesterday, as I was tracking a Baltimore Oriole and a Prairie Warbler through the branches, I caught sight of yet another bright yellow bird. I watched and watched until it showed itself to be a Blackpoll.
The morning sun also makes them look more yellow making for added flashes of excitement in the hunt.
I thought it might be a good time to share the array of images of variable Blackpoll Warblers I have collected throughout this season.
Despite the many variations, there are several field marks that remain the same. There is a line through the eye, except for the male in breeding plumage.. There are always wing bars, but the easiest way to confirm this species quickly is to check the legs and feet.
Almost always, they will appear bright yellow or orange.
While the numbers of this species, like other warblers, are diminishing, there are several still in the mix....just the spice things up.
