THE British Trust for Ornithology, the country's leading body for ornithological research, has come up with an on-line advice guide for the millions of ordinary people - and their children - who take a keen but amateur interest in the subject.
And it could provide the right answers for some of the more obscure debates that sometimes break out between "twitchers" - as keen birdwatchers are known.
- Need to know how many eggs a Nightingale lays?
- Need to know the weight of a Mute Swan?
- Need a quick link to population changes for Song Thrush?
- Need to know the Icelandic name of the Black-tailed Godwit?
- Need some little-known, fascinating facts?
Answers to these and many other questions can now be found on Dr Rob Robinson's new section of the BTO's website called BirdFacts (www.bto.org/birdfacts), bringing together lots of information on the UK's common (and less common) birds.
