Tree swallows are very common around Copper Dollar Cove and are sometimes mistaken for bluebirds. They are sparrow sized birds with blue upperparts but have clear white underparts. They like to live along lake shores, flooded meadows, marshes and streams. They like to move into the bluebird houses especially around the sewerage ponds by Copper Penny Lake. That is another reason why the bluebird trail needs to be checked at least once a week to remove unwanted nests before eggs are laid. The tree swallows nest is very similar to a bluebirds nest but it also contains feathers. Their eggs are also white instead of blue. We let a swallow family nest in one of our boxes in our backyard and we were able to watch them from the building of the nest to the four fledgelings that took off last week.
