Evening garden watch

Spent half an hour counting the birds observed from the garden. I used the RSPB garden watch method of counting, whereby you only count the largest number of birds seen at any one time. This, therefore means the same bird is not counted more than once. However, it does give the lowest possible count and in this instance, probably an incorrect count for several species, especially jackdaw and wood pigeon. Results:
rook 1
jackdaw 7
great tit 3
collared dove 8
starling 7
house sparrow 3
blackbird 2
blue tit 4
dunnock 1
chaffinch 2
robin 1
greenfinch 1
wood pigeon 2
song thrush 1
pied wagtail 1
goldfinch 1
pheasant 1
17 species in half an hour (5.30 - 6.00pm)
