Deceased Backyard Bird Id?

Kay Voyvodich

Greetings Sf Birders,

I would like to know if it is ok to post two photos here of a deceased bird I found in my backyard for identification and guesses to cause of death. Rigor mortise had not set in so I was able to photograph the underwing open.

Thank you for your help. Typically when I find birds I have taken them to the Academy of Science but I gave this little one an honorable burial.
