March Highlights: Great Northern Divers, Bewick's and Whooper Swans, Merlin and Peregrine, Godwits, Glaucous Gull, Sand Martin and Swallow.

The 2 long staying Great Northern Divers were still both present on 29th and presumed present all month. Bewick's Swan are now a rare event at Carsington, so 24 on the water near Stones Island on 9th attracted some attention before they were disturbed by boat activity at 1020hrs. The whole flock lifted, then circled for half an hour gaining height before flying on southwards. It was way back in December 2003 when Bewick's were last recorded here. Thankfully Whoopers are a more regular sight, with a flock of 33 first over Sheepwash, then over the Ranger Base on 24th, and another flock of 12 over the Visitor Centre on 25th. Wildfowl counts showed that many ducks have left site to journey to their breeding grounds. Maximum numbers this month were: Wigeon 106 on 8th, Gadwall 3 on 18th, Teal 7 on 24th, Mallard 62 on 18th, Shoveler 3 on 3rd, Tufted 236 on 18th, Goldeneye 12 on 18th, Goosander 2 on 5th, Moorhen 39 on 18th and Coot 215 on 18th.

Raptors have shown relatively well this month, with 2 Sparrowhawks from Sheepwash on 8th, 6 Common Buzzards over Hall Wood on 13th, a female Merlin near Hall Wood on 20th, an immature Peregrine on 5th and 30th and a Peregrine from the Wildlife Centre on 19th.

Oystercatchers have claimed breeding territory, which is usually a whole island per pair at Carsington where the islands are small. They were seen mating from 11th, and 10 individuals were noted on 18th and on 26th. During operational work on 26th, over 20 Snipe were flushed up from Sheepwash Spit. This probably helped the following day count of 22 total between the Wildlife Centre and Paul Stanley hide. Other wader records included 1 Dunlin at Sheepwash on 7th, 1 Woodcock in Warrington Knob on 13th, 1 Black-tailed Godwit at the Wildlife Centre on 10th, 1 Bar-tailed Godwit at Paul Stanley Hide on 19th, 51Curlew at dusk at the Wildlife Centre on 1st with 34 still there on 27th, 9 Redshank on 26th and a Common Sandpiper on 25th, presumed to be a wintering bird.

A first winter Glaucous Gull on 5th was the only notable gull this month. On 16th March there were 2 records of 2 Sand Martins, which is consistent with other sites. There were no further records of Sand Martin until the 29th when 2 were noted. This gap was obviously due to adverse weather halting the migration progress. Swallows also started passage, with the first record being 10 on 29th. A presumed wintering male Blackcap was near the main car park on 31st and presumed spring migrant Chiffchaff were in evidence, with 8 singing on 14th and 11 singing on 26th. The Starling roost at Kirk Ireton quite rightly drew in many observers, with up to 50,000 birds, and with balls of birds being targeted by sparrowhawk and peregrine, it was well worth experiencing. By the end of the month it had all finished. On the 2nd, 30,000 starlings, in various sized flocks, were counted flying over Carsington Water towards the roost. The bird feeders around the site have been attracting the colourful Bullfinch, with 6 on Sheepwash feeders on 10th. Also a female Yellowhammer, which is now a rare sight at Carsington, was on these feeders on 28th, together with male and female Reed Bunting and other finches.

93 species were recorded this March compared with 100 in 2006, 107 in 2005, 98 in 2004 101 in 2003 and 96 in 2002. The low species number is due to some migrants which usually arrive in late March delaying to April and very few gull species were seen this month.
