@Biotope_Tormod I've recently got back from Mongolia and off to Portugal end September -- Prof Colin and one of my team Liz are there from about 5th September
@HalfSnipe@RichardIves18 Been monitoring them for about 6 years now on my day roost only site- currently 30+ birds there most are near little puddles but few actually in them. You can see the site on my Winterwatch segment.
@GeorgeMWME@BBCSpringwatch We have several different models- if you would like a chat about the pros n cons try to get your number to me in private (sorry not good with social media) and I'll gladly get back
Colin
