All nations have the right to govern themselves
It's one of those mind-blowing news items that birds pull off every so often, like the Bar-tailed Godwits flying non-stop from Alaska to New Zealand, the 90,000-km-a-year Arctic Terns, the Nutcrackers that can remember exactly where they hid 100,000 pine nuts last autumn (and still find them under a metre of snow!), and that birds can see magnetic fields (and hence also compass directions) as 'colours'. Things that just totally beggar belief, and would have been dismissed as fantasy just a few years ago.Indeed, that was something new! Particularly that one hypothesis is that they can hear (or feel) infra-sound.
According to the wildfowl warden, all the (pinioned) Black Swans remaining on Dawlish brook are males. Didn't stop two of them building a nest last month, opposite the appropriately-named Gay's CreameryI was amazed to read that 25% of Black Swans exhibit homosexual behaviour by paring up with fellow males once eggs are laid.
Chris, can they do that in all situations or only when the head wind is strong enough to drive them backwards?
Not sure if this is appropriate for the forum, but I did stumble across it one day, and I found it quite interesting..
A male Lake Duck (a relative of the Ruddy) may use its very long corkscrew genitalia to lasso unwilling females to force copulation..
