BTO House Martin Survey 2015

See http://www.bto.org/volunteer-surveys/ho ... urvey-2015

This will involve volunteers visiting 2,000–3,000 ‘random’ (i.e. pre-selected) 1-km squares throughout the UK.

By surveying random squares, the BTO will be able to assume that our results are representative across a wider area, and produce a robust population estimate against which changes in the future can be measured.

How can YOU help?
The BTO needs volunteers who are willing to carry out two or three visits to a 1-km square between late May and mid-July, to look for House Martins and their nests.

How long will each visit take?
The survey 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. Each visit will normally take around two to three hours - however, the visit length depends on the habitats within the square and visits to urban squares may take longer.

Many of the squares only have one building to visit so it should not be a difficult task but unfortunately many are in remote areas so any help would be much appreciated. The first visit should take place between 1-24 June, and if no nests are found no further visit will be required. If nests are found a second visit will be required to check which nests are active and this should take place between the 25th June and the 19th July. Recording will be on line and this should be up and running next month. As negative results are just as important as positive ones all visits will need to be recorded.
