Yellow-rumped Warblers are some of my favorite winter guests. These little lovelies typically arrive in October and hang out til early spring.
You can see why they are affectionately referred to as “Butter Butts” in the picture below.
Like many of my backyard birds, these guys are big fans of Bark Butter – a suety type spread that I get from Wild Birds Unlimited.
Lately, my Yellow-rumped Warblers have been acting more like Yellow-rumped Warriors, dive bombing any other Warbler that dares to enter their no fly zone.
As mating season approaches, their colors will start to darken, which is just beginning to take place in some of them.
Here are a few pictures from last year so you can see what I mean about the darker tones.
Besides their buttery backsides, these Warblers also have patches of yellow under their wings and beneath their head feathers.
I like having these guys in my backyard…their appearance is beautiful and their antics are entertaining.

Terrific images, Kathy!
These warblers are colourful and showy! Almost all the warblers that occur here are non-descript and very shy. But they all have a beautiful voice. Does the yellow-rumped warbler have a beautiful song too?
How timely to see your lovely images of these warblers from recently and, by comparison, from last year, Kathy. I was able to capture a few warbler shots on a recent hike, and I think some of them are of yellow-rumped warblers. I always rather assume so if they have those striking butter butts! 💛
