Out & about early this morning with a great start with Northern Wheatear (male) whilst walking the dog (My earliest ever) Then headed over to Shustoke Reservoir picking up several Chiffchaff (migrants? or dispersing winter birds?) Then onto Coton lakes where I had a Chiffchaff which ticked all the boxes yet again for Sibe Chiff (Tristis) even the song was different but recorded & sonogrammed & bird is a mixed singer!! (What is going on out there??) Sonogram below for those who ain't fell asleep!!
