Noisy Friarbird nest

A few days ago I noticed that a Noisy Friarbird was frequently visiting a pin oak in our garden.  On applying my binoculars to one of its visits I realised that there was nest there.

Today I set up my telescope (with phone-camera adapter) on the spot and was very surprised to see up to 3 chicks poking their heads up.  My surprise arises because:
  • the nest has obviously been in operation for about 3 weeks and I hadn't noticed it; and
  • fencing contractors have been working  - including using a JCB backhoe - within 5 metres of the nest.
Here are a couple of photos.  The first just shows the nest.
 If you look closely at this one the head of a chick is just visible: the eye and the yellow gape are the things to look for.
I will try and get some clearer shots on a less windy day!

On Christmas day it was much cooler and in my checking of the nest I couldn't see any chicks. I was seriously hoping that a Currawong (Strepera graculina illegittima) hadn't raided the nest.  However on Boxing Day the adults were still coming to the nest and sticking their heads in.  Then an adult arrived and settled down to brood.


From about Boxing Day it became a bit tricky walking across the lawn as the adult birds practiced their swooping tactics.   More fencing work happened on the 27th and 28th and on the evening of the 28th I made it across the lawn without being swooped.  Had the adults abandoned the nest?  My next trip across the lawn gave a major swoop, so all is OK.  In addition, unlike the Pied Currawongs the Friarbirds aren't sexist: Frances also gets swooped.

Quite late in the evening of the 28th there was a large amount of Noisy Friarbird calling from the top of the Big Yellow Box.  At least 3 birds were up there calling and flying about in an agitated manner.  Eventually a brown Goshawk departed with the 3 Friarbirds in close formation behind it.

It isn't just raptors and humans that get chased: on the evening of the 30th December a pair of gang-gangs came into the garden and were immediately harassed by the friarbirds.  As Gang-gangs don't look like raptors, and don't fly like raptors, this must be some instinctive reaction to movement in the vicinity of the nest.

We walked across the lawn on 4 January and didn't get swooped!  A there had been more fencing going on we were unsure if this meant the chicks had fledged or if the parents had given up and abandoned.  Checking from a stepladder the nest was empty so a successful event!

November 2017

It is astonishing how often clicking the button to send the brief report to the Editor of the Gazette causes an exciting bird to appear.

I still think our second-ever report of Scarlet Honeyeater (image from Avibase)  ...
.. has to be bird of the month.  Two birds were seen on Wanna Wanna Rd.  They have been seen regularly in Canberra this season.  (Further afield there is a massive irruption in  Victoria.)

However to hear that Banded Lapwings have been spotted on the Plain (Western side this year) was a big surprise.  4 birds were seen on 30 November, and 5 on 1 December.  Some of the birds appeared to be sticking to one spot so may be nesting, despite the paddock being well-endowed with cattle.

With those as highlights there were a bunch of other goodies also seen:
  • Cattle Egret,  Brown and Rufous Songlarks on the Plain;
  • Brush Cuckoo, Eastern Koel Red-capped Robin and Nankeen Night-Heronat Whiskers Creek Rd; and
  • Masked Woodswallow at Knox Close.
Given this extensive list of " unusuals" it was a bit weird to find the overall diversity a little below average.
It appears that the major group of MIAs are waterbirds.  Of the 38 species seen at least once in November only 16 (42%) seen in 2017.  Numbers and diversity have been very light on Foxlow Lagoon and some of the other hot-spots have become physical and metaphorical dry-spots!  It is particularly noticeable that most Herons and their relatives (Ibis; Spoonbills) are missing.  Presumably they are still undertaking procreational duty at the swamps of the Riverina.

Nearly all migrants have arrived, with Western Gerygone (hard to identify),  Rainbow Bee-eater (which often travels up the Molonglo as a passage migrant, but not this year) and the very uncommon Channel-billled Cuckoo the only ones yet to be reported.  Of the 29 species 17 arrived on time, 6 were early and 2 arrived late.

23 species were observed breeding.  I was excited to see Sacred Kingfishers starting to excavate a nest hollow in a Yellow Box near our house ...
 ... which counts as a possible breeding record.  They appear to have given up, which has made our live a lot quieter.  However a pair have taken up occupancy of a hollow in Knox Close.  My family of Tawny Frogmouths have left the nest ...
..  as have broods in Knox Close and Wanna Wanna Rd.

Breeding species are shown in red text in the list below.

As always, thanks to the observers who have provided reports to me for the month.  These have covered sites in Douglas Close, Whiskers Creek Rd, Widgiewa Rd, Knox Close, Wanna Wanna Rd, Molonglo Valley, and Hoskinstown Village and Plain.  Please pass on interesting sightings to me by email to martinflab@gmail.com.
