Since this post contains a couple of photographs, I figured I'd put it in "The Darkroom".
We don't seem to have a Weird Lifeforms -- or Not? forum, so work with me here.

This has appeared on one of our windows on the first floor.
Mind you, I have two degrees nominally in Biology, but I have no idea what this is.

Kind of reminds me of a mitochondrion, but it is rather too large. :p
The color and fine structure make me think it's either an egg mass of some sort, or a critter of some sort -- or maybe it's just bird droppings(?).
The better photo gives no sense of scale. I tried to add a ruler for scale, but I had trouble with focus (depth of field). This photo is inverted relative to the one above.

Whatever it is, it's about 13 mm/0.5 inch long.

Anyone have any idea what this is?

:p
 
Yeah looks like an egg sac. Googling egg sac results in hundreds if not thousands of photos of different ones.
I suppose you could narrow it down by your location.
