Bird survey needs your help

The British Trust for Ornithology’s House Martin Count Survey 2015 needs volunteers to count numbers of the summer migrant which usually nests under the eaves of houses in mud nests.

The survey has selected random one kilometre squares in which it wants people to count the birds and their nests from late May to mid-July. Two or three visits will be required.

A spokesperson said: “The survey visits will involve walking around the square looking for House Martins and their nests and mapping and recording a few details about any nests that you find.

“In most squares each visit will normally take around one to two hours. However, the visit length depends on the habitats within the square: visits to urban squares may take longer, whereas visits to squares with only a small number of buildings may take less than half an hour.”
