Mjolnaton Canadian Geese 3
Aug (Can't) And continuing to honk now and then. One by one they started to feed, putting their heads down into the duck weed. Honking became less & less till all was quiet. One big one kept his head up, looking all around as if he were a guard, but soon he put his head down and fed like the rest.
I shot one. Its stomach intestine was full of ground up green plant. In the gizzard was a little of the ground grass or weed. In the crop was the broken parts of the duck weed and short grass like blue grass. Also there were amphipods.
I broke up a clump of this grass + duck weed. The soil around the tangled roots was about 80% sand. There were quite a number, perhaps 50 amphipods to the square foot. Found one earthworm like animal. It had a tougher outer cuticle than regular earthworms.
