RECORDING SWALLOW NUMBERS

I have been getting reports of swallow decline  in some areas and good swallow numbers in other areas.  So  I am trying to find a way to put all the information together as the reasons could be complicated. I have found out that

The British Trust for Ornithology  have

1, Bird Track page at  http://www.bto.org/birdtrack/

Why not take a look and enter your swallow information there as at the moment I don’t have any means of putting all the information together – except by typing it (which I may do!)

 Here is a link to view the results  –

 Have been  trying to see if there is a way to record all the swallow information I have received on my website and on my forum.   Wouldn’t it be great if we could.  Have looked at google maps and a site called Abundance Maps,but  the BTO are doing this recording which will help us understand the changes in swallow numbers.

I  spent time looking at  two mapping details  and I have put links below.   I do not think they are the best way to record the information and as I am not truly technical I did not understand them completely.

Our swallows will soon be gone.  For the past few years their numbers have declined.  I wish I knew why.  Because swallows cover a wide area of this Planet Earth it could be a variety of reasons.

    Swallows and house martins

    On looking back to some of the reports on the breeding of these species I wonder if the nests are being identified correctly? It is swallows that build a cup nest and usually use the interior of a building, whereas house martins is an enclosed mud structure on the outside of buildings, such as eaves or the apex of a house.
    Over the twelve years I have been ringing swallows as a BTO project I have only had one occasion where a swallow nested under the eaves using the usual cup nest. This was at a site one year when there was pressure for finding a site, as there were a dozen or so pairs setting up home.
    The sad fact is over all those years it is only about 30% of adults that manage to return and breed, but they regularly come back to where they first nested. The young birds have a greater failure rate and tend to not breed where they were hatched but do turn up within a 2-3 mile radius.
    At the end of this month May I have one swallow nest where the eggs have hatched, and are also bit later this year in Worcestershire.
