Ivy is a very "English" female name but Ivy got his name because he is fourth (IV) generation Radisson male. And yes, his name is spelled "Ivy" not "IV", the latter is just too impersonal. Took a chance naming him this, no way to know if he would survive to actually be a fourth generation breeding Radisson bird.
How will you decide when to "take a chance" and specially name a Radisson male chick of the fifth generation, since Ivy (the fourth generation) is now a breeding
Radisson bird.
I don't really name birds with an eye to name each generation, T-Rex's band was 1/X and he reminded us of the Jurassic Park velociraptors - in fact, the movie came out the day before we went to band chicks of his and my boss at the time got pummelled by this tiny furious peregrine. The name was a no-brainer I'm afraid, bird never changed. Trey got his name because he came back the year after hatch just like his dad and he was actually named for being third generation male to come back - not because he was third generation at the Radisson. Ivy got his name more because he had a V in his band and I often try phonetics for band numbers but there really isn't a phonetic for a sideways 8. Considering half or more of all chicks don't make it through their first year, it could have been a wasted name. Having said that, there was a bird we didn't name who I thought was a slam-dunk to replace T-Rex but he crashed into a building here in town when he was three. A bird I knew would replace Trey was Sherpa but he too died in a fluke accident when he was six. So much more competent birds died while Ivy, who is a bit of a passive bird, survives to take over the Radisson - maybe because of his name? Who knows.
In any case, no immediate plans to name a fifth generation as such, but we'll see. Maybe there will be a bird that just jumps out and says "name me"!!
