The Birds Of South Gloucestershire          Black-necked Grebe - podiceps nigricollis

 

Black-necked Grebe is known in North America as Eared Grebe and one of its folk names is in fact Eared Diver. It breeds in vegetated areas of freshwater lakes across Europe, Asia and Africa. In the cooler temperate regions of the Old World they also winter further south, with many European birds moving to the Mediterranean area. The first reference to the modern name Black-necked Grebe was in 1912 when it replaced the term 'Eared Grebe'. Some historical names for Black-necked Grebe include; Black Grebe and Rolling Pin. Black-necked is a direct translation of the scientific name 'nigricollis'.

 

There have been three Black-necked Grebes reported from S. Gloucestershire;

 

1999: (1)

One was reported from Oldbury Power Station on April 4th.

 

1997: (1)

One, a moulting adult was seen on August 31st at Oldbury Power Station on Lagoon III. (DH Payne)

On October 24th a single bird was seen drifting up the R. Severn off New Passage towards Aust Warth on the tide. This occurrence constitutes the first report of this species for S. Gloucestershire. (Paul Bowerman, Dick Reader)

FIELD NOTES

 

On the evening of Thursday 24th October 1996 while walking past the small jetty at New Passage, I saw a small, basically 'black & white' grebe about 150 yards out on the river, drifting upstream on the incoming tide. Realising that this Black-necked Grebe was a first for Severnside, and with Brian Lancastle on Scilly’s for 'teachers week' I tried to phone Paul Bowerman, but all I kept getting was his voice mail service (he was at a fun fair at Cribbs Causeway apparently, and could not hear his phone ringing !!) after leaving several 'impolite' messages, I phoned the news to 'Flick Dilby’s' pager service hoping that Paul would hear, or feel, his pager going off! That did the trick and a few minutes later he arrived at New Passage, looking a bit shaky on his feet, and sporting some extremely baggy tracksuit bottoms, the legacy of a rather painful 'man's operation' from the day before! Unfortunately for Paul the bird had continued to drift upstream past Northwick Warth and towards Aust Warth, and was becoming distant from New Passage. So we went to Old Passage and relocated the bird near the old Severn Bridge where we watched it until dusk.

 

DESCRIPTION

 

Body: Short, with 'blunt' rear end and when preening, or just resting on the surface, having a 'fluffy, puffed up' appearance similar to that of Little Grebe. Breast white, upper body greyish-black, flanks, and rear white, mottled with blackish-grey.

 

Head: In profile – a steeply rising forehead to the crown, crown then curving uniformly rearwards and down to meet the nape. Crown black, black extending down to below eye level, and onto the ear coverts. Cheeks and chin white.

 

Neck: White at lower front and sides, some blackish-grey extending from the nape onto the upper neck sides, fading downwards into white on the lower sides of the neck. Rear of neck black, extending from crown to upper body in a narrow central band.

 

Bill: Blackish with the lower mandible curving upwards to the bill tip, creating the impression of having an 'up-turned' bill.

 

Eyes: Red.

 

Size: Difficult to judge in isolation, but was approximately three quarters the size of Eurasian Teal, as the bird drifted past a small raft of them on the water.
