Pale Headed Rosella Nesting

What a marvelous contribution, Brian. With nesting hollows being destroyed at a fast clip bird species which depend on them need all the help they can get.

Not trying to hijack the thread but I'd like to add my experience with these beautiful birds.

Some 12 months ago I placed a nest box high up in the eaves at the back of the house. It took a while but eventually a pair of pale headeds began to visit more and more often to the point where at this point in time one bird (presumably the female) spends most of the day inside the box. The other bird visits maybe 4 or 5 times a day and they fly off together. 

What is perplexing is that for the last two or three days, almost right on dusk the male arrives and they fly off together. Try as I might I cannot see if the female comes back but unless they fly at night, the nest is empty overnight.

Has anyone seen this behaviour in their own locale? Surely if she has laid anything the egg(s) wouldn't cope with the lack of warmth overnight? I would assume that the breeding imperative would be paramount but maybe as first timers......?

You can be justifiably proud of your achievement, Brian. With so many of our old growth trees & their hollows being destroyed  birds which require hollows for their breeding need all the help they can get. 

It seems the Pale-headed Rosellas in your area feel quite secure in using your nest boxes. Nice.

From our observations I am confident that our resident PHR has hatchlings, or very near so. Over the last couple of days the male has arrived three or four times a day and the female is away for no more than 10 minutes at a time, flying back into the nest box directly, wasting no time in entering.

Fingers crossed that we see the results at some stage and that they don't fly off while we're at work! The local butcher birds and kookaburras are also vitally interested:

A healthy biodiversity should enable the Pale-headed Rosellas to sustain their population notwithstanding any predations from Kookaburras & Butcherbirds.

So far so good, here she is keeping an eye on our dogs in the back yard. The nest box is effectively 3 stories off the ground but they're still wary.

Sorry not to have commented on the recent threads DaveF, I have been otherwise occupied.  Hope you have a similar success to us and am confident you will. 

About 2 hours ago our first rosie for the spring 2017 season fledged.  This September mother rosie laid 4 eggs and hatched 4 babies.  We still have 3 in the nest, but we expect them to be gone by tomorrow afternoon judging on past performances.  I saw the first egg on 4/8/17 and then first saw the babies (probably a couple of days old) on 1/9/17 and first baby fledged 28/9/17.

That is 27 fledged rosies we have helped in to the local enviroment since September 2013. I will choose a nice red for happy hour for the proud defacto grandparents.    Brian DJ

Well done, Brian & Pale-headed Rosellas! I trust that elsewhere in the local environment people are restoring habitat for the new Rosellas so that existing habitat isn't over-taxed.

It seems your Pale-headed Rosellas haven't been disturbed by people looking in the nest box to count the eggs & hatchlings.

During breeding season I'm tending to avoid anywhere that looks like a breeding place for birds to  minimise nest abandonment - except in the case of Blackbirds, Starlings, House Sparrows, Feral Pigeons & Spotted Turtle Doves, of course!

Our rosie breeders appear to trust us and though I do look in to the nest several times during breeding times to check how many, stage of development, etc., it has never been a problem, but I am careful to only do it just after I see the parents leave so they don't see me. 

All 4 rosie babies now fledged, last  one yesterday.  We saw 2 of the 4 babies fly away and am amazed just how well they fly on their first flight, nature is marvellous, there must be some great school lessons in that box from hatching to fledging. 

While we don't see any extra rosies in our area since they started breeding at our house (young obviously taught that this is current breeders area and young must go elsewhere) other people in the estate comment that they have noticed more rosies around their area and we are also lucky that there is plenty of bush in our area.  Wish I could attach a transmitter to each new baby rosie so I knew how many are still around.  Brian DJ

Thats awesone Brian, I only hope that my pair are as productive! My box needs a tall extension ladder to get close to, I curse that I didn't make plans for a webcam of something so I can see what is going on inside. After the season is over this year I'm going to see what I can arrange.

Lots of movement noise from inside today, so I hope that it's juveniles, not just the female cleaning house so to speak.
