This morning, another little bird, another Vaux's Swift came down the chimney. It is fat and healthy, so I did as they suggested in the Wildlife Care Center. I picked it up and I reached as far up the chimney as I could and placed it against the side so it would cling to the bricks and creep its way back up to its nest. It grasped onto the bricks when I let go of it. See Marley in the background? The little birds make him nervous. Either he is worried that this one is a rat - the little swifts screech and screech at times - or that he will get into trouble in some way to do with the little bird. This is a photo of the previous bird to fall from the nest. I didn't take a photo of the one that fell today because I wanted to get him back up the chimney as quickly as possible. Also, it isn't a good idea to handle them unless they need rescuing or feeding. If you look closely at the bird's tail (click on the photograph to blow it up), you can see little spines at the tip of each tailfeather that the chimney swift sticks into whatever it is clinging to.
I have gone back to the fireplace many times to listen and try and discern if the little bird is okay and will keep watch over the next days to make certain it has not fallen down the chimney. It appears that it has climbed farther up the chimney from where I placed it. Every day, we can hear the calls of the babies as their parents come down the chimney from above. So much so, you'd think they were inside the room.
