Covid-19

Hi All
Just to let everyone know we are cancelling all volunteer days for an undetermined period. As most of the volunteers are of a certain age and most have health issues it seems prudent to hold off for awhile. The Sunday Cabin will also be closed for now. 

Thanks for your support.

CBWG Chair

The Reserve will be open for walks as normal. Always maintain at least 2 metres from others.  STAY SAFE

March Flowers

As volunteering sessions are suspended for the foreseeable future I spent some of my social distancing time on Thursday walking around the reserve to see what flowers are out. Here is a selection.

Next to the car park there are a number of Flowering Current (Ribes sanguineum) shrubs currently in flower. It's a garden escape which seems to have very successfully escaped to Cromwell Bottom. If you look closely at the pink flowers you will see that they have five outer splayed petals, and five inner petals that form a tube. They are in hanging racemes (flower cluster with the separate flowers attached by short equal stalks). The leaves have 3 to 5 rounded lobes.


There are many Blackthorn (Prunus spinosa) trees around the reserve. They are usually smallish looking more like a large bush than a tree but can be easily recognised at this time of the year as they have white flowers but no leaves. The white flowers contrast starkly with the black or very dark wood (hence the name). The flowers have five rounded white petals with numerous stamens.


During the year the Sloes develop which can be picked in Autumn to flavour your gin or make Sloe jam but watch out for those sharp thorns!

One of the earliest dandelion look-a-likes to appear in the year is Coltsfoot (Tussilago farfara). You will see it flowering without leaves, the disproportionate sized leaves appear later usually after flowering has finished. The stems are scaly and sometimes red.


See this picture of a Dandelion (Taraxacum agg.) for comparison, a few early ones are already out:



2 members of the Buttercup family are currently displaying.

Marsh Marigolds (Caltha palustris) have been out for several weeks already. You can see them in the course of the disused canal opposite the dipping ponds, they like wet conditions. They look like very large buttercups but with large very un-buttercup like leaves



Lesser Celandines (Ficaria verna) are just appearing, they are low growing and are in a number places in the reserve, the one I photographed was by the river. The number of yellow petals is variable, the outers are green tinged. The leaves are glossy and heart shaped.



There will be much more to emerge in the coming weeks.

Below are all the reported bird sightings for Cromwell Bottom nature
reserve in January 2020. Many thanks to all who contributed, most
especially Mike Henshaw and Jeff Milne.

Highlight is undoubtably the over-wintering chiffchaff but the long
staying water rail on the lagoon is also worth a mention.

55 birds in total.

A few highlights worth mentioning:
1) A few years ago the trustees set themselves the task of trying to attract a few key species to breed on the reserve for probably the first time. Success was achieved in definitely attracting barn owl and probably attracting skylark. Much work has gone on behind the scenes to attract these locally rare breeding birds to the reserve.
2) Sightings were made of 2 different egret species. It is not many years since these became regular visitors to southern England but they are now moving further north. It will not be long before they become regular visitors to the reserve?

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.)

2nd January 2020

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?
