There will be many readers for whom this is a new expression. There will be others who will have heard of it, but are uncertain about what's involved. Well, all that is to be remedied!

Vis-mig itself is undertaken by a few hardy souls who, mainly at dawn or dusk, will station themselves at suitable sites (##) during the migration periods, in order to monitor the species and their numbers as they pass through the skies.
*
(##) Suitable sites tend to be on higher ground with unobstructed all-round vision, and away from noise. The latter is to help facilitate the hearing of call notes of each species in order to positively identify them.

It is my intention to have somebody come and speak to us about the subject, but it is likely to be in the 2011 - 2012 series of Winter Lectures - we have no vacancies until then!
*
In the meantime I would encourage you to visit :-http://vismig.blogspot.com/
Where, apart from anything else, you will find links to about 160 similar sites, many, or most of which relate to the same subject. By the time the lecture comes round we should be conversant with the subject and be able to appreciate it all the more.

It's a fascinating subject - take a look.*
