Manitoba Peregrines - Family Tree
The Peregrine Chick:
Easiest question first ... we haven't named all the birds in our Project over the years. Most have in recent years because of increased public interest in the birds and that more of our birds are nesting/sighted elsewhere. Ivy's and Lucy's is Finity - her band number is sideways 8 (the sign for infinity) over Y. Calling her Infinity was just courting disaster, the only time a peregrine is infinite is when its dead.
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. Trey got his name the same way - Trey was/is Radisson male III generation. Ivy's band number is sideways 8 over V, so Ivy is also a good mnemonic. Sometimes the bands are the reason for the names, sometimes its another reason.
Does that help?
Kinderchick:
I'm not sure if this is where I should post this question, but I was wondering how Ivy got his name? ??? Cilla Kinross, Project Coordinator for the recovery project in Orange, NSW, Australia asked me about Ivy, since Ivy is traditionally a female name. Was it that you thought that Ivy was a female at the time of banding, TPC? I went to the Family Tree and noted that Trey & Princess hatched Ivy in 2005, along with Lucy and another female chick. And I myself am wondering why the other female chick was not named? ???

TPC answered this awhile back so I'll just repost what she said:
Most peregrine don't live into their teens, heck half don't make it to their first year. Most that do make it to year 2 don't make it past 10 years old. That applies for males and females. Oldest bird in the wild is I believe a male who made it to 19 years plus some months I believe. Survivorship for Falcon peregrinus anatum is about 80% per year after second year. That means that at year 10, 11% of all the birds hatched that same year are still alive, at year 20, only 1% are still alive. Median age is 4.5 years for both genders. Most of our breeding birds last a wee bit longer than that.
And I will add this to TPC's post : Sir James in Richmond, Virginia is the oldest peregrine alive right now in the wild that we know of - he is 20 this year!! Here is an article on him from last year when he broke the record at 19, he's just awesome!! This year, he and his mate Elizabeth produced 5 chicks again!! there are also a few famous pairs down in the US that are between 12-16 years of age, we have a female here in Toronto from the US that turned 12 this year - but these falcons are the exception to the rule. As TPC and the James articles state - average lifespan is only 4-5 years of age.

ShoeChick:
I just had a read through this thread and followed the link to the Raddison family tree. I see that Trey was born in 1996 which would have made him 13 last year when he fathered his last nest that we are aware of.
This got me to thinking how long can Peregrines live? I know that there are several factors involved, so maybe the better question would be what is the longest that they are known to have lived?
