First Migrant

Not surprised that the first spring migrant of this year, heard this morning, was a chiffchaff. The weather has turned very mild so that we have bats flying up and down the lane in the evenings. Blue tits are building in the nest box just outside the kitchen window. Heard yellow hammer singing and the chaffinches are singing away. The flock of chaffinches is still around but I have now been able to determine that they are mainly females. The males are establishing their territories and presumably their mates wil accompany them soon.
