Brewster's Warbler – Jeremy Meyer Photography

These warblers are spectacular when seen in the field, especially the male GWWA with his strong face pattern. I usually have the GWWA warblers feeding on the ground, picking through dried curled up leaves, looking for spiders. This year was no different. Warnimont Park is my favorite to find them doing this, in particular behind the archery range, just north of the golf parking lot. If you don’t see them on the ground, their song is quite easy to pick out, seee-bzzz, bzzz, bzzz, which is quite loud and easy to track down. on 5/11, I had 9 of them at Warnimont Park. The BWWA is usually higher up in the trees, but I also have them feeding on or near the ground as well, similar to the GWWA. This spring I was lucky enough to have a BWWA come down right in front of me and take a bath in the creek at Whitnall Park. Splashed around a bit and up and away he went! Warnimont Park is usually loaded with BWWA’s and I had 6 on 5/11. Although I didn’t fair as well as I usually do with them and photos. They are also easy to track down by song, as it is a very loud beee-bzzzzzz! They often seem like they are closer than they really are. The Brewster’s Warbler is a hybrid between the two species. It is the more dominant trait and is quite common where the species overlap. Brewster’s Warbler looks like a GWWA but has the black line through the eye like a BWWA. The one I saw this year at Warnimont, came on 5/11 and was the prettiest one I’ve seen. There was a lot of white on the throat, which really added to the overall coloring. Surprisingly, I see this sub-species just about every year and I’m always excited when I do. Someday, I would really love to see the Lawrence’s Warbler, which is the recessive trait of the two. Photos below are from the last few weeks in the Milwaukee area. Enjoy!
