Fallen seeds

I saw quite a lot of these pinky/red-tinged seeds on the ground as I walked through the woods today. Are they Sycamore seeds I'm wondering. Seems a bit early in the year for fallen Sycamore seeds, but maybe they're immature ones? I'll have to do a bit of reading to try and find out about them. I really like the look of them anyway.

My extra is looking through the trees at Reelig House again. I've blipped similar views of this a couple of other times, but on much gloomier days!
