Linacre Reservoir - 27th February 2021

 It was a bright, sunny and calm morning this morning, with a temperature of just 1 degree at 7am, as I arrived at Linacre. I spent 2 hours walking around all three reservoirs, by which time the temperature had risen to 5 degrees.

The first birds seen were a flock of at least 30 Redwing (first Linacre record of 2021) feeding in the fields by the main entrance. The woods were alive with bird song, including 2 Mistle Thrushes, 1 Song Thrush, Nuthatch, Green Woodpecker and 2 drumming Great-spotted Woodpecker. No Lesser-spotted Woodpecker or Chiffchaff, despite much searching and listening!

Out on the water, waterfowl numbers were still pretty good, with 111 Tufted Duck, 106 Mallard, 79 Mandarin Duck, 4 Canada Geese, 4 Great-crested Grebe, 4 Little Grebe, 3 Goosander (1m and 2fm), 32 Black-headed Gull, 14 Coots (excellent count!) and 5 Moorhens.

I did a nestbox check on 17th February. I only checked the tit boxes, as I didn't have the ladders for the owl boxes. Most were okay, after the winter, and 1 contained a Shrew species, most likely a Common Shrew.

Common Shrew?

Linacre Gull Fest and WeBS - 15th February 2021

 This month's WeBS walk at Linacre Reservoirs took place yesterday. Following a week of very cold temperatures (+2 maximum) and snow there was a lot of ice covering all three reservoirs (c.40%), which made counting easier, and also lead to some excellent records.

First up, the waterfowl counts: 148 Mallard, 105 Tufted Duck (my highest ever count, possibly cold weather movement?), 102 Mandarin Duck, 12 Moorhen, 9 Coot, 1 Cormorant (in full breeding plumage), 4 Little Grebe, 10 Goosander (4 males and 6 females), 168 (minimum, most likely 200+) Black-headed Gull (including 2 metal-ringed birds and a darvic-ringed bird),  2 Lesser Black-backed Gulls (both adult-type, returning breeders from Chesterfield?), 1 Herring Gull (flew over the top reservoir for 5 minutes - only my sixth record since 2006!), 1 adult Common Gull, only my third ever Linacre record, previous records being in 2014 and 2016 and 2 Grey Wagtail. 

Common Gull (and Black-headed Gull)

As you can see, the number of Black-headed Gulls was fantastic, probably due to me being on site until 2.00pm, and because of the icy conditions elsewhere, as were the Herring and Common Gull records. Lesser Black-backed Gull sightings have increased in  the last few years, as they have established themselves as a breeding species in Chesterfield (first confirmed breeding in 2018 I think) and will continue to grow as the breeding population increases. The same may happen for Herring Gull, as they too, have become a breeding species in Chesterfield too.

Whilst scanning through the Black-headed Gulls, I spotted 2 metal-ringed birds and 1 darvic-ringed bird. Unfortunately, I couldn't read the metal rings (too far away), but I did manage to get a distant photo of the darvic-ringed bird, and saw that it was 2T46. This was a bird that my nephew, Luke, saw at nearby Holmebrook Valley CP, on 6th November 2020, and had been ringed in Grange-over-Sands, Cumbria, on 19th September 2020. The first photo is this bird in November, whilst the second is from yesterday. Luke's photo was taken much nearer (!), whilst my photo shows how the bird's breeding plumage brown hood is developing.

Other birds seen/heard around the reservoirs were: Tawny Owl (heard), Raven (2 displaying), Green Woodpecker (heard), Skylark (1 seen and heard over the top reservoir), Common Buzzard (3 together), Sparrowhawk (1 displaying), Stock Dove (4, and singing heard).

NOTE: a Lesser-spotted Woodpecker was noted (not by me!) on 14th February, feeding with a mixed tit flock - the first 2021 record.
