Second-earliest GARGANEY arrive at Amwell - Diary Notes entry for LGRE


Although temperatures in the south climbed to 7.5 degrees C, a cold easterly wind made it feel very bitter. It remained bright throughout, with long spells of sunshine and clear blue skies.

Recent days have heralded the arrival of spring with many waders returning to breeding localities, including Curlew, Common Redshank, Lapwing, Oystercatcher and Ringed Plover, as well as some early returning migrants such as Little Ringed Plover, Northern Wheatear, Sand Martin and White Wagtail. There has been a wave of coastal GARGANEYS but it still came as a surprise when Alan Reynolds telephoned to say that Bill Last had discovered a pair at Amwell - a very early date. Frustratingly, I was in Dorset, and a mere 198 miles away........


Three LITTLE EGRETS were still lingering today, along with a single CONTINENTAL CORMORANT at Bois Mill Lake.

(1600-1630 hours)

As soon as I returned from Dorset, I drove over to Amwell and was very pleased to see that the two GARGANEYS were still present and showing well. They were an adult pair in pristine fresh spring plumage and although asleep on some branches for most of the time opposite the Tom Gladwin Hide, both birds (and accompanying pair of Common Teal) were rudely awaken by an Atlantic Canada Goose, which hissed and chased them, forcing them to relocate a few yards away. Joan Thompson joined me in the hide, with both birds still showing well when I departed at 1630. Garganey represented my 200th species of 2010.

There have been instances of wintering by Garganey in Hertfordshire on three separate occasions, including a long-lived drake which survived from 1997 until January 2001. However, in terms of genuine immigrants, today's pair are the second-ever earlies arrivals, following the drake at Amwell on 2 March 2003.

Also at Great Hardmead Lake this afternoon were 8 Grey Herons, 6 Mute Swans, 38 Eurasian Wigeon, 15 Common Teal,18 Gadwall, 12 Shoveler,112 Tufted Duck, 16 Pochard, 8 Common Goldeneye, 5 SMEW (an adult drake and four redheads) and 6 Great Crested Grebes.


The adult female PEREGRINE was roosting in its usual spot and showing very well (see Dan Forder's superb array of new images above).

A41 (HERTS) - dead Badger on westbound A41 near Dudswell.


No sign of the Red-crested Pochard pair but 11 Great Crested Grebes, 2 adult Mute Swans, 105 Shoveler, 3 Tufted Duck, 5 Northern Pochard and 3 Coot; some 62 CORN BUNTINGS roosted.


Four Great Crested Grebe, 76 Coot, 22 Tufted Duck and 30 Northern Pochard.

(1745-1825 hours; with Steve Rodwell)

The number of roosting gulls has decreased dramatically with just 1,200 Black-headed Gulls estimated this evening, along with 87 Common Gulls and 6 adult Lesser Black-backed Gulls; Steve located the 2nd-winter MEDITERRANEAN GULL, this bird being the same as that present on 27-28 February and photographed by David Bilcock above. It has some blackish feathering coming through on the head, with a blood-red bill and black band and black primary patterning.

Two LITTLE EGRETS flew in to roost on the Drayton Bank, whilst wildfowl included 8 COMMON GOLDENEYE (3 adult drakes), diminishing numbers of Eurasian Wigeon (just 214) and 18 Great Crested Grebes, 6 Gadwall, 26 Shoveler, 96 Tufted Duck and 38 Pochard.
