Like other warblers, the Black-throated Blue Warbler (Dendroica caerulescens) is highly territorial during breeding season. Gentlemen lose their gentlemanlyness when other males encroach on their territories. Often, vigorous battles erupt, with the males chasing one another from the highest points in the canopy down to the forest floor. These disputes can last hours...or days! The ladies, like that photographed here, must sit in nearby branches and shake their heads disapprovingly at this childish behavior.
Admittedly not a great photo but it's a juvenile wren from the moose birdhouse nest below our deck that I've been watching for a couple of months and just about gave up hope. This little guy and his mom were hopping around on my porch this morning...really happy she finally had a cluch of eggs hatch. Sorry it's blurry but he was everywhere at once and very curious. So cute...hope to see them up on the porch again soon. Yay!
