What: I went back and set the game cam up further back from the fence. It doesn't quite capture them crawling under the fence (I put it too far back), but it does give a pretty good sense of how curious and observant they are. They definitely, in both this video and the previous one, noticed the game cam and spent time to investigate it.
Ecological notes: The three or four beavers that live in the pond are two pairs. The second pair moved in about 4 weeks ago when UVM Facilities destroyed the habitat surrounding the other constructed retention pond by the Sheraton. With no food the beavers headed down stream, found this pond and took up residency with them.
I think that two of the beavers were siblings (one from each pair). And I think that they're probably also the same beavers that were living here last spring. Sam and I have both been watching the beavers in the spring, and it took time to earn their trust (where they wouldn't slap their tails at us). I would assume that this beaver remembered me (and the trust it had for me), which is why it only took a couple times to have it come right back up to me.
Where: Retention pond in Centennial Woods.
