Notable Absence

I spent a few hours at my window today to see how many species I could see from the house in a day, my record is 36 species in 24 hours which shouldn't be too difficult to beat in the autumn. Today I managed 29 species in total but with some notable absences such as Black Headed Gull (I get flocks of 200+ sometimes in the autumn and winter feeding in the fields) as they have all moved off to their breeding sites now. The full list from today with the highlights (in garden terms) in bold:
