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.

October 2017

The most exciting sighting this month was a huge flock (~200 birds) of White-browed (see above) and Masked Woodswallows which turned up at our place for a few hours mid-month.   White-winged Trillers vary in their abundance: some years none, other years they are everywhere.  This year they seem to be in good numbers. Those species and a few others are covered in an ad-hoc blogpost.

Red-capped Robins have been seen at our house on a few occasions recently.  The most recent visit is covered by a post. A White-fronted Chat was seen beside Hoskinstown Rd (where Banded Lapwings resided 2 years ago).

There has been a further Grey Goshawk sighting, off Captains Flat Rd (not far from the Molonglo).  I wondered if this was the bird reported in September was following the River but the first sighting was a grey bird, while the one in October was white-phase.  Two members of this species in the area is quite exciting..  

Overall 102 species of birds have been recorded in the month.  This is pretty much on average - quite an achievement considering the dry and/or blackened state of a fair chunk of the study area.
Thinking about the level of diversity I record the species occurring each week in a 3Ha area based on our house and keep a cumulative tally of the number of species seen since the start of July.  This year the diversity began quite low - up to 8 species below the average.  However in mid-September (GBS week 38) a bunch of species were added to the list and its just kept growing.
In terms of breeding, I have received reports of 18 species at various stages of the breeding cycle.  The most interesting have been Sacred Kingfishers in Knox Close, Olive -backed Orioles copulating in Wanna Wanna Rd and Australian King-Parrots inspecting a hollow on the Community Plant Walk in Stoney Creek NR!   After spotting an egg under a very agitated dad on 19 October ...
... there is now at least one chick is in the Tawny Frogmouth nest in our yard.  
An unusual breeding record was a pair of Pacific Black Ducks standing on the muddy shore of a dam with an egg between: intention clear, execution appalling.  The species observed breeding are shown in red text in the list below.

Of the regular migrants 12 of the expected species have returned on time, one “usual“ was late and six have been early.  2 less common species have not yet been recorded.  Overall, I’d  rate it as an early year.

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

Red-capped Robins

I will update this post with some links etc but wanted to get the images up quickly.

As we returned from our dog walk this morning I heard the distinctive 'Drrt-drrt' call (sometimes called the "old telephone call") of a Red-capped Robin.  On gathering my binoculars and camera and returning to the site I soon spotted an adult female of the species.
 Note the rudimentary red patch above the bill.

She stopped calling and flew into another tree from which she chased another very similar bird.  I was able to locate the other bird and here are a couple of images.  Although it didn't call, and it doesn't have the red forehead, I believe this to be a second female (possibly a younger bird).

Despite searching for several minutes I was unable to locate a male of the species.

Woodswallows and Trillers

An exciting visit of about 200 White-browed Woodswallows is covered in this post in my main blog.  Here is a taster snap.

September 2017

The most exciting sighting this month is a Grey Goshawk seen between Stony Creek NR and the Molonglo.  This is only the second sighting of this species in the area. 

A number of other less common species have also been recorded including White-bellied Sea-Eagle (flying over Whiskers Creek), Black-winged Stilt (seen from the road at Foxlow Lagoon), Powerful Owl (Wanna Wanna, flying into Cuumbeun) , Red-capped Robin (Whiskers Creek), Yellow Thornbill (Whiskers Creek) and Varied Sittella (Whiskers Creek).  

In total 90 species have been recorded, a little below average for the month.
It is tempting to ascribe the reduced number of species in recent months to the weather.  Very low rainfall will have reduced the food resources and horrible strong winds make birds seek shelter and thus be hard to spot.  That being said one observer reported:
 ... the upside of the wind at our place is that we have watched some kestrels do some amazing aerial acrobatics! Remaining in a stationary hover in 50k/h winds and then diving in a straight line and swooping low to return to 100m... it's truly amazing. ""
In terms of breeding, I have received reports of 14 species at various stages of the breeding cycle (marked in red text below), mainly nest building.  On average this cycle appears to be happening about on schedule, with the number of early records balancing the number of late species.  The records are a little "thin" so I'd welcome any additions. I haven’t yet found a nest of Flame Robins but they are still around in the same places, after being difficult to spot mid-month.  

Linking the breeding cycle and migration, Fairy Martins are a little early returning and are building nests in the usual spot.   An unusual element of migrant return were the large (by Whiskers/Widgiewa standards) flocks of Yellow-faced Honeyeaters heading West.  We recorded 150 on one dog walk, which is more like Autumn departure than the more gradual return.  Of the regular migrants 11 of the expected species have returned on time, two are late and four have been early returners (so on average everything is normal - or perhaps a tad early).  Those seen have orange highlight below.

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

Start of Tawny Frogmouth nesting

I have been monitoring the breeding activities of a pair of Tawny Frogmouths since 2008 - a period of 10 years.  I have good measures of when nest building started for 7 of those years.  Of the other three years:
  • 2008 was the first year and I didn't realise the nest existed until I spotted the male in incubation mode;
  • 2011 the nest site moved to another tree, and again I didn't realise what was going on until the male went missing and I found him incubating.;
  • 2014 had - I now think - a false start, in that some twigs were blown into the nest site and gave a misleading picture.
For this year the birds seemed very late in starting their activities but on 6 September 2017, when we returned from Mallacoota, there were a few twigs in the nest fork.  On the morning of 7 September more twigs had arrived, but they hadn't yet been trampled ...
... so I am taking 6 September as the start of nest building.  (If they had started while we were away I think it would be no more than one day earlier.)  This is the latest date I have recorded: counting back from the date of fledging chicks 2008 may have been later but making assumptions like that is a very slippery slope.

This year has been pretty dry and - in terms of average minimum temperature - quite cold.  I wondered how these factors went in explaining the relatively late start on nest building.

I have daily data on rainfall, maximum and minimum temperatures for the period 2009 to the present.  I used this to build some data for analysis:
  • total rainfalls and average extreme temperatures for official Winter (June to August) and my version of Winter (July and August); and
  • number of days since 1 January to start of building
for each in-scope year.  On looking at the correlation coefficients it seemed that the 2 month weather data correlated more closely with the date of starting than the three month values so the shorter period data form this table (actually an image of a table)
The correlation coefficient for rainfall with date of starting building is quite strongly negative, suggesting that the lower the rainfall, the higher the number of days (ie the later the start of nesting).  The correlation for minimum temperature with date of starting is not so strong but again suggests a cold year gives later nesting.  The coefficient for maximum temperature is too weak to be considered.

The data can be plotted on a graph.
From my inexpert view this reinforces the idea that rainfall in July and August is the most important factor (of those I have assessed) in determining the start of nesting.

As the breeding event proceeds I shall look at other benchmarks (start of incubation and nest being empty).

August 2017

As we start to move into peak breeding season (to mis-spell as  'peek' with 'birds' and 'breeding' in a post should boost my click count) here is a photo of the force of evil gathering nesting material.
It seemed to have pretty strict selection criteria judging by the number of twigs it picked up and put down.

Also breeding are Masked Lapwings, as evidenced by this egg-laden nest from Widgiewa Rd.  Thanks for the observation and the image Sandra.
On average it appears that breeding is pretty much on time as shown in this image with two species early, three late and 4 on time.  "Uncommon" relates to breeding being rarely recorded, rather than low frequency of observations.
In the month list below breeding birds are shown in red.

While there have been no “rip your shirt off” rarities this month the sightings of Flame Robins have provided considerable interest particularly in the Widgiewa/Whiskers Creek area.  Although I had not recorded the species on our block before this year an observer on Widgiewa Rd reported that they have been seen there occasionally.  Towards the end of the month this species also became entwined with the seasonal matters of breeding activities and returning migrants. 

In total we have recorded 83 species for the month.  

As expected a good jump from July.  It is a little below average with a few quite common species (Silvereye and Red-brown Finch being examples) not being recorded.  In terms of records around our house I scored a large number of additions to my (financial) year list early in the month, with a mixture of returning migrants and less common birds being recorded.

Migrants are beginning to return with all 6 expected species turning up (although Grey Fantails only appeared very late in the month).  2 species have made an early return.
The Horsfield's Bronze-Cuckoo record was interesting as it was two birds seen feeding on the ground and being mobbed by Flame Robins, suggesting the robins were breeding nearby. 

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