American Black Tern......

Sunset over the nearby Lincolnshire Wolds.

After hearing that GPC had found this first for Lincolnshire,a frantic dash to the res,resulted in everyone present enjoying stunning views of this nearctic visitor.The bird was watched feeding,hawking insects over the res for the majority of the time we observed it,but it did have a few periods of rest on adjacent fields loosely associating with the flocks of Black-headed and Common Gulls present.It was on occasion chased by the local gulls,but managed to evade them thankfully.It was an interesting bird to study,with the distinct i.d. features obvious such as the greyish wash along the flanks,grey underwings and more 'smudged' mark at the neck side and the head pattern was more reminiscent of White-winged Black Tern,a cracker and a fantastic find!.Although there is some argument about it's taxonomic status,it was still an enjoyable and educational bird to watch.Other birds seen while enjoying the Tern included an adult and juvenile Red-necked Grebe(Also possibly of the american race) which showed well and 4 Common Sandpiper.An excellent few hours at this great site.
