For our weekly bluebird check, Bob brought his grandson, Calvin along. This week we found 30 bluebird chicks, some might leave the nest in the coming week. There are many tree Swallow nests on our trail. As we traveled our trail, we came upon a box with a house sparrow in it. Calvin said "A house sparrow! what does he think, I thought it was a bluebird trial or does he think it's a house sparrow trail?" It was a great visit to the trail with Calvin along.
