|Robins nest made mostly of mud with|
twigs, grass, and bark strips (Ruby Mtns, Nevada)
Robins can have two to three clutches in a year, so I'm assuming that this is the second or third for this female this year. In general male robins are a darker gray, with a darker patch of slate on top of their heads, females tend to be browner. Lots of sources I read just parrot other sources, so I don't know how reliable they are. Apparently males have more robust streaks on their throats than females, but I don't know how reliable this is since it's a relative comparison. I'm in out of town right now (the photos are a couple days old), but when I get back I'm excited to look closer at their throats. Since the females are the only ones that sit on the eggs, that should be a pretty easy thing to study. The one sitting on the Males are definitely the only ones that sing though.
Where: My backyard
Other notes: Robins are one of three types of birds we have that use mud to build their nests, phoebes and swallows being the other two in Vermont. I've watched a robin dip a stick in mud and carry it to the nesting site. You can see in the above photo that the nest also incorporates twigs, grass, and strips of plastic. Phoebe and barn swallows are pictured below:
