Hi folks,

This was about 1.5 m up from the ground in a damp woodland and approx 50 m or so from the nearest standing water. Remote location so i'm sure it was nothing anthropocentric.
There were no signs of any claw marks of an animal climbing up the tree, and nothing further i could detect on the tree limb, nor any sign of disturbance underneath either.

Any suggestions whodunnit Will, Caleb or anyone? A heron? Seems a very low branch for one of those, but i'm no bird expert!

On upper horizontal branch, centre right of pic:

Hi Ben, I love a mystery! kids? they have been known to chuck frogspawn around. The lack of any entrails / other signs is puzzling - normally there's some viscera left over if the poor frog has been nabbed by a crow, rat etc. Maybe there were some frog remains higher up the tree? (heron might have perched at the top and the egg mass went splat onto the lower bough - a 'tree down' hypothesis, rather than 'ground-up' if you see what I mean?)

I'm told that herons always eat their prey whole, and regurgitate undigestible bones etc. as pellets like owls do. I'd guess that any frogspawn they might regurgitate wouldn't look as clean as this.

'Tree down' is a good theory, I vote that Ben should climb the tree to look for any frog entrails.

Thanks guys, 'tree down' may be right - should have thought to look up. D'oh! No chance of returning there tho' Caleb. It's miles away. However, herons certainly regurgitate spawn. I tastefully posted some pics of heron regurgitate from a field trip with HART (the Hereford ARG) a couple of years ago, and there was some among it, along with bits of frog and invertebrate cases.

Very good Keith.
