How can I help birds
 

 

There is a few things you can do the first thing is join the R.S.P.B or "The Royal Society for the Protection of Birds" in doing so you will receive  a  free gift normally a bird feeder and a great quarterly magazine called "birds". but the best thing is you get a membership card that allows you in to all the R.S.P.B reserves free. The money it makes goes  back in to helping birds. Here is some info about the R.S.P.B from their site

"Since its founding in 1889, the RSPB has grown into a wildlife conservation charity with more than a million members. It has offices across the UK and, since its successful first campaign to end the plumage trade, it has widened its sphere of influence to include a huge range of issues that affect wildlife and habitats.

The RSPB: 

  • Works with decision makers on behalf of birds and the environment 
  • Researches wildlife problems and promotes practical solutions 
  • Protects, restores and manages important areas for wildlife across the UK 
  • Works internationally through a global conservation partnership called BirdLife International 
  • Shares expertise and knowledge to help young and old enjoy the natural world 
  • Tackles wildlife crime and habitat loss 
  • Works with landowners and farmers to help countryside birds"

   It is really worth joining and you will be helping birds too.

There are other groups like the R.S.P.B. The B.T.O  or "The British Trust for Ornithology"  is one of them here is some info from the B.T.O site.

"The British Trust for Ornithology

The British Trust for Ornithology has existed since 1933 as an independent, scientific research trust, investigating the populations, movements and ecology of wild birds in the British Isles. Our speciality is the design and implementation of volunteer wild bird surveys. Our partnership between a large number of volunteers and a small scientific staff has proved to be a powerful, productive and cost-effective way of monitoring wild birds. Volunteers of all ages and from all walks of life put their bird-watching skills to good use. They record wild birds systematically using survey methods developed by our scientists, who then compile the records and analyse them for publication. This work makes a direct and vital contribution to bird conservation, by enabling both campaigners and decision-makers to set priorities and target resources. It also provides a unique insight into the state of our environment and how it may be changing."

 
A way you can help birds in your area is by joining you local ornithological society most counties have them Hampshire has one called H.O.S or the "HAMPSHIRE ORNITHOLOGICAL SOCIETY".  I can only speak for H.O.S as I am a member but I would expect the others are much the same there are news letters and  reports you will get you can submit your sightings to them. and there are meetings and walks you can attend all in all it is well worth it.
 
but the probably the most important thing is put up nest boxes and put out food for the birds there is lots of info on the R.S.P.B site and there are lots of reasonably priced mail order companies that will sent you your food and nest boxes as do the R.S.P.B.
