I sometimes lack the gumption to take photos, and to post here. The last few weeks has been one of those times.

I found this cute little frog on a windowsill about 3 feet off the floor inside my workplace this morning. My co-worker and me speculated on how it came to be there and did not arrive at a satisfactory conclusion.
A little research revealed that it’s likely a Gray Treefrog. After a while I took it outside into (what to this human seems to be) a better place for a tree frog.

I’ve had a problem with songbirds, especially American Goldfinches, flying into my living room windows – the fixed portion and the casement windows on each side of it. Thankfully I’ve never seen one killed.
I bought a kit with a roll of clear tape which has small dots embedded every 2”. You install a length of tape the length (or width) of your window, use the supplied mini squeegee to press it down, peel off the clear tape and the dots are left behind on the glass. Move over 2”, install another length, repeat until the entire window has dots spaced 2” apart. The dots are a visual cue that this is a solid that you can’t fly through.
This is a huge, huge problem, particularly during migration seasons, in cities with reflectorized windows on mid- and high-rise buildings. Fatal Light Awareness Program (FLAP Canada).

Before. To a bird this casement window looks like open air.

And after.

I do hope this helps.
