"Smudge", Our Resident Western Gull

A few days after we got home from our Thanksgiving in Las Vegas, we began noticing that a single gull was returning every day to our deck. At times he would try the seed in the feeder (then gack it up), but mostly he just preened and sat and stared at us (and our cat) through the window.

Here he is on December 7th, 2013, a few days after his appearance.

I thought he was a Herring Gull, and posted the following photo of him on Oregon Birds - discovered that he is a slightly smudgy WESTERN GULL.

Taken 1/6/2014 - he had been hanging around about 4 weeks

Some days he "talks" to us, or to our cat "Don Diego".  Mostly, he just sits watching us through the window. In the above photo, you can see the protruding feather that lets us know it's the same gull.

Taken 1/16/2014, he had damaged his bill and was bleeding slightly

Today, February 10, 2014, he is still returning to his regular spot.  This photo, taken yesterday, shows how he has changed. 

"Smudge" is not so smudgy anymore!

Most of the smudginess is gone!  Getting ready for breeding season?

So now I am curious how long he will be coming around - and how long will we know it's the same bird?
