A great article on Hybrid Zones. The Fox squirrel is an introduced species,where as the Western Gray is a native. http://www.macroevolution.net/hybrid-populations.html#.UUNErje6F1g
ForestDragon,the Ranger of Mt Diablo says that hybridzation between, Fox and Gray is a possibility.
Nice educational post Hemma!
I did a search online on several resources from different states and could find no information of Fox and Gray squirrels interbreeding. That's not to say that it hasn't occurred, I just don't know. What I did find is that both Gray and Fox Squirrels have several color phases which can make it more confusing for ID at times. https://www.farmanddairy.com/columns/squirrels-know-persistence-pays-off-in-the-end/14201.html
I agree that this is a Fox Squirrel. No doubt in my mind either. The physical characteristics are consistent: http://www.projectsquirrel.org/gray_fox.shtml
Thanks for this great and interesting information,Phil S.!!
I am certainly not as familiar with the western grey as I am the eastern due to my location but there are two distinct factors that convinced me this is a fox squirrel. Coloring is number one. Although both greys and fox can have a frosted look to their fur on their backs, greys will more often than not have a white belly. Again, some greys have displayed rust colored or redder bellie so I then look at the tail. Greys will have a more frosted look to their tails whiles foxes will have either a black outline on the tail or black mixed in the the tail which would not be seen in a grey. You can learn more here: http://www.projectsquirrel.org/ and also of course at the Project Squirrel mission here on Noah http://www.projectnoah.org/missions/36002
Phil S, I was studying images on the net and I do feel that this is a Fox Squirrel. I have updated the Id accordingly. Thanks for your feedback.
Do not see any obvious tufts in ear.
Looks more like a fox squirrel to me.
Three species of tree squirrels live in the Bay Area: the Eastern Gray Squirrel (Sciurus Carolinensis), the Eastern Fox Squirrel (Sciurus Niger), and the Western Gray Squirrel (Sciurus Griseus). Of these three, only the Western Gray Squirrel is a California native, and its status is of concern to naturalists. http://www.wcsv.org/education/species/western-gray-squirrel/
David looks like it is a hybrid. Western Gray Squirrel x Fox.
Wonderful. I took a picture that is very similar. The squirrel either had over eaten, was exhausted, or was enjoying sun bathing too much to be bothered by my coming closer.
