New Years Day Annual Bird Count and Walk

I



I am taking the liberty of posting this on the Cromwell Bottom Blog because two members (or a member - MC - and her husband,) were keen enough to join us on 1st January, and Margaret found the final bird of the day, a male Bullfinch, making the count equal last year's record.

The regular route is from Clay House Park, through North Dean Woods, around Norland Moor and back throught North Dean by a different path. (About 7 miles.)

These New Year's Day Bird Counts have settled into a run of consistent results. This year and 2019 had equal numbers of species with 32; in 2017 the tally was 31. Fine weather is a factor. Given a foul day the count would be lower obviously; we have been lucky these last three times.

As above the two last counts were 32 and it is interesting to look at the similarities and differences in the two counts.

There were 23 species in common to both counts, 1st Jan 2019 and 1st Jan 2020:
Blue, Great, Coal and Long-tailed Tits, Nuthatch, Chaffinch, Bullfinch, House Sparrow, Starling, Blackbird, Mistle Thrush, Redwing, Robin, Collared Dove, Woodpigeon, Feral Pigeon, Jay, Crow, Magpie, Jackdaw, Rook, Black-headed Gull, Buzzard.

Nine species in 2019 but not 2020: Dipper, Dunnock, Wren, Raven, Pheasant, Stonechat, Little Owl, Mallard, Song Thrush.

And there were nine species in 2020 but not in 2019: Heron, Goldfinch, Reed Bunting, Fieldfare, Redpoll, Treecreeper, Great Spotted Woodpecker, Greenfinch, Common Gull.

The Fieldfares were in a huge flock covering two fields, very impressive, and the Redpolls were flitting charmingly through the trees along the top of North Dean Woods feeding from the birch seed-heads.

With thanks to the participants in the walk yesterday, 10 in total (8 in 2019.) All played a part in the final count on the walk as well as bringing their sightings from home first thing and on the way to the meet (without detours to sites with localised species.)

Two of us thought we heard a single note from a Green Woodpecker at the lower edge of Norland Moor where they are often present, but it was very brief so I decided not to include it.

There was some discussion whether to include domestic fowl, etc. I maintained they are bird species, others thought we should stick purely to self-sufficient wild or feral birds.

The bad news about the Little Owls adjacent to Norland Moor is that Jackdaws usurped them from their tree hole last spring so that's probably why we didn't see them all summer or this winter. Jackdaws in tree holes have become the norm throughout Calderdale. At one time I used to see them using only holes in old buildings and crevices in quarry rock-faces, where they still nest.

These counts are samples of the current state of local birds. Who would have thought a few decades ago that Nuthatch and Buzzard would be seen regularly? Also to run into a Raven isn't that unusual now, and to find a Song Thrush or a Greenfinch is a fairly noteworthy event.

These records might be interesting to read in the future. Another way of "sampling" bird populations is to time a count on a walk, noting every species. I seem get about 14 species on a good day in half an hour, though I haven't sat down with my notebooks to work out the average. It's OK to count a bird if you identify it without doubt by its call or song. The habitat needs recording; upland, waterside or woodland, etc.

Perhaps we could initiate a regular Spring Bird Count every May-day on 1st May?
