This my first experience with either species but on ebird both have been seen here within the past day. most are probably brewer's sparrow as they are more likely here but I am hoping for the clay colored. one thing that might be of note is that two people have hinted that there may be two clay colored sparrows. Mostly just hoping for confirmations to my IDs.
number 1 and 2, Clay colored sparrow on the right(1st photo), brewer's on the left
numbers 3 and 4, clay colored Sparrow? seems to have complete eyeing and white crown-stripe
number 5, brewer's sparrow
