Used to be well known! 😎
Must be fun for (mainly southern hemisphere) birders monitoring nests at this time of year, hatchling #2 is a 1 cy while its sibling a day older is 2 cy πŸ˜‚
Lol But hatchling #1 is 1 calendar year younger than it’s sibling only until tomorrow so it won’t matter - unless of course, hatchling #1 and hatchling #2 are ringed today in which case, in several years time, if both are recovered, someone might have to look twice at the data to realise they were from the same brood! πŸ€“ Happy New Year!
