Locustella naevia - scarce summer visitor 

Grasshopper warbler was found to breed in all 21 10km squares in the survey done for the 1968-72 Atlas.   In the '87-89 Tetrad survey however it was only found in 26 tetrads [out of 391] and confirmed to breed in just five. The decline of gropper in the county is merely a reflection of a general contraction of the species within the UK. This can only partly be explained by a loss of habitat and, as for many species, research at their wintering sites may supply the answer to their increasing scarcity

The favoured habitat is marshes and reedbeds and they are most commonly found in river valleys - the Kennet in particular

In the most recent county report there were records from seven locations with all but one coming from mid to west of the county. Generally, ringers are the best source of information about breeding and the group at Thatcham reported a f/w bird in August

This year has been fairly typical with the first record around the 20th of April and reports coming from Thatcham & Wraysbury

There are two birds in this series - both at known sites in the east of the county
