Green Birding (and Nature) in Central California: gulls

Sunday, April 4, 2010

Bird ID Challenge # 3

This photo was taken on the San Luis Obispo County coast in February. Please let me know your IDs and the reasons for them by clicking on "comments" at the bottom of this post and then posting your thoughts. I will post what I think the IDs are on Wednesday evening, but gulls are admittedly not my strongest area of identification so I will be interested in your comments. Have fun.

See the "comments" for my ID, which is rather tentative for the back gull.

The Purpose of My Blog

I have created this blog to document my attempt to bird in as environmentally friendly fashion as possible, and to encourage others to do so. In 2008 I did a Big Green Big Year - BIGBY (268 species) and I decided to try and break 300 species in 2010. I walked, biked, ran, and kayaked from home (in coastal California) without using any gas, and at the same time recorded (and tried to photograph) the birds I saw. Most of this blog documents that incredibly fun, and at times very challenging, green big year. I ended up with a green big year total of 318 species in 2010 (see the list below). Since 2010 others have done much more impressive green big years! I have continued to do green birding. I have participated and organized green birding events such as the local Elfin Forest Big Sit and have promoted green birding by leading bicycle birding trips at the Morro Bay Winter Bird Festival. Lately, I have continued with green birding from my home and have entered my checklists on eBird (see the article of March 28, 2015).

All species I saw or heard on 2010 Green Big Year were in San Luis Obispo County except for those with a "K" which were only in Kern County - seen on a ten day bike ride from home and back. The date first recorded in 2010 is noted (w=on walk from home in 2010). W = all species I have seen or heard walking from home any year. G = all species I have recorded on green trips from home any time:
