There were some photos (I deleted) of them feeding there even after it was dark. Then a fox (probably Gray Fox) appears. The cage bars sure weren't a deterrent to the fox. (The top of the cage is covered with the slanted wire panel.) At first I thought the fox is eating a dove, but I don't think it could have captured a dove inside the cage with the impediment of the wire. That's a stake in front of his head that holds the cage in place.
A few minutes later a javelina tries to uproot the cage.
Then the fox returns.
