Twin Brothers


These two amazing Wedge-tailed Eaglets hatched on a nest built by the parents of Wailitj - the Perth Hills' first juvenile eagle to be satellite-tracked - about a month ago. Given that Wailitj only survived for 2 months post-fledging, it was thrilling to discover his parents had doubled their 'output' this season.


At the end of September, with the help of some beautiful young boys (sons of some Perth Hills friends of mine) who have been keen to learn first hand about my eagle research, we fitted this brood of 'twins' with colour rings, weighed and measured the birds, then made ourselves scarce. With both having reached the age of 5 weeks, the odds were that they should continue growing healthily to fledging age of 3 months, but nothing is certain in the ever-changing natural world.

I was very excited to return to their eyrie this morning with my great friends Mick and Rianna and their two young sons Jarrahn and Bhodi, and find both eaglets (now juvenile eagles!) still alive and well! We fitted these birds with satellite transmitters - the second set of 'twin' WA wedgies to be sat-tagged - and I paused to photograph the partially consumed ibis on the eyrie as I placed them back 'home'. With this nest site definitely having the theme of 'two boys', I decided to give Jarrahn and Bhodi some homework: to come up with names for each eagle, with the only rule being that (as with all my Perth Hills eagles) they had to be in Noongar language.

The next day Mick rang me to let me know that the birds were to be called Naakal (= quiet) and Ngooni (= bother), two very appropriate Noongar words. It will be a privilege to follow the movements of these young brothers when they fledge and begin to wander around WA. I wonder if they will stay together on their journey?!
