This is a very unusual sight. Deer tend to herd during the winter,
and then the herd will tend to break up as the does have fawns.

We've never seen a deer "yard" except in books.
this YouTube shows a small deer yard:

But this Yahoo video is very different!
Wait til the end for the surprise ending...

In summer we have seen our few deer --- females chasing males off when they are taking care of fawns. They try to keep the food for themselves since nursing is a dietary stressor.

We've had deer this year in the city in our yard! They are eating my black eyed susan seedlings! This plant, Rudbeckia, is on deer resistant lists, but that is not stopping our city deer! They are all lined up on a bench where I can tend them. Next to them are petunias (which I am keeping in pots to take on vacation)...and they are spared. UpNorth, the deer LOVE petunias.

I have been frustrated by the deer this summer here, as I start many of my plants from seeds and nurse them along..only to be devoured in one night? groan!
