No, this is actually a Song Sparrow that is molting and has
lost all its tail feathers. Its pretty
easy to fall into thinking that these summer days are a little boring in the
birding world, most of the birds around us we have already identified, it’s too
early to get to see the new fall arrivals , and yet there are some very
interesting things that are taking place.
During the last couple of weeks Matt Hunter has alerted us to watch for birds with missing feathers and the molting process
that goes on this time of year. As is turns out, all birds go through a molting
process at least once, some twice a year.
It’s important at some point that their old worn feathers are
replaced. For migrating birds, this time
of year is crucial so that they get new feathers before they start their migration
south. However, Song Sparrows are year
around residents, so I’m not sure what the importance is to this timing. We have seen this Song Sparrow hanging
around the feeder for the past week. My
first thought was that there had been a narrow escape from a predator and in
the process had lost its tail feathers. My second thought was that perhaps it
was a chick that had left the nest before growing tail feathers. After consulting with a couple of experts it
was decided that this is just a part of the molting process. If you look close
at the photo you can see a number of the other feathers are in state of disarray.
Soon it will have all new feathers and look perfect once again.
