"Curious Winter Wren" by Debra Martz
Like any Wren I’ve ever watched, this one was curious, too. It was under rocks, between rocks, in the vegetation, hopping in the water puddle, and exploring every knook and cranny in the area. Finally, it briefly stopped!

A small brown bird, Winter Wren, stands on a sunlit rock beside a flowing stream, casting a delicate shadow. The sunlight highlights the bird's feathers, creating a contrast against the dark water in the background. Photography by Debra Martz

Note: Not to mention, this was a Lifer, which made my day of birdwatching complete!

Great tit chicks being raised by Blue tit parents? Uncommon, but it happens.

However, research shows that being raised by foster-parents has life-changing consequences for Great tit chicks.

Great tits raised by Blue tits fail to pair with conspecifics

Great tit chicks raised by Blue tit foster parents stayed unpaired or paired with Blue tits later in life.

While most birds come flying in and zipping all about, this Orange-crowned Warbler just appeared to be out strolling along the limbs, interspersed with a little foraging for insects along the branches.
