2018 Annual Report

This will be a little shorter than my usual annual reports as I am somewhat preoccupied with the final stages of moving from Carwoola.

The "big-ticket" item in a year's observations is how many species were recorded.  The answer for the Gazette catchment area in 2018 is 156.  This is the same as in 2017 and is the third time we have reached this number, the highest since 2007.
The first two years are mainly personal records and the pattern is largely constant since  that as other observers have joined in.

Three taxa were added to the list this year: Spangled Drongo (Wanna Wanna Rd); White-throated Nightjar (Hoskinstown) and Hybrid Crimson x Eastern Rosella (Whiskers Creek Rd).  This gets our total taxa recorded to 198.

Looking at the species recorded each month emphasises the pattern I have remarked on over the last year.  For the first half of 2018 we recorded average or better number of species, but in the second half of the year the number of species per month declined.
I am inclined to blame this on the continuing drought, with the number of waterbird species in particular dropping significantly in December and some migrant species (especially insectivores)either not turning up or being infrequently seen in the Spring/Summer. 

I have classified the species to 9 broad groups (mainly for ease of presenting the monthly lists).  The number of species.  When looking at the pattern of number of species reported each year by category an interesting pattern emerges.
5 of the 9 categories show a similar pattern over the years with occasional ups and downs but essentially constant.  The category "Other larger birds" with 8 members, is constant with all of the species seen every year.  The small brown bird category (thornbills, finches etc) is also close to constant ranging between 18 and 21 species per year.  Waterbirds have shown the greatest level of increase - possibly reflecting discovery of better sites in the area over time.  Birds of prey also show a steady increase, although they have been sparse in most months of 2018.

Since 2007, 101 Species have been observed undertaking some form of activity classified as indicating breeding.  A very low 35 species were recorded breeding in calendar 2018.  

Birds are not unduly fussed about calendar years, organising their breeding around a season with  good food supplies - effectively a year ending in June.  Looking at number of species recorded breeding for year ended June  ...
.. shows the last complete season to be about average.  However the number of breeding records for the start of the 2018-19 season is very low.  Again I attribute this to the ongoing drought.

Looking at individual species in 2018 cf other years 42 species are missing in 2018.  Most of these were relatively rare in the past (35 of the missing species being recorded in ,10% of months).  Those recorded more frequently but missing in 2018 were:

  • Brown Quail (possibly due to mis-identification of Stubble Quail on some occasions in the past);
  • Musk Duck - shallow conditions in Foxlow Lagoon unsuitable for this species;
  • White-throated Needletail - always an occasional species, very related to storm fronts.
  • Spotted Harrier - shortage of prey species on the Plain;
  • Speckled Warbler - lack of insect food?
  • Southern Whiteface - lack of insect food?
  • Golden-headed Cisticola - lack of rank grass habitat on the Plain.
In the past 16 species have been seen every month.  In 2018 one of these. White-eared Honeyeater was not reported in 2 months.  Of the other 22 species previously seen in 11 months or more per year only 1 - Little Pied Cormorant was not reported every month in 2018 (due to the parlous state of most dams).  Basically, the common birds remained common.  

The overall comparison between reporting rates for 2018 and earlier years is shown in this scatterplot:
The relationship is quite strong with an r2 of 0.78 for the linear trend.  I have marked an outlier 932% of months prior to 2018 but every month in that year. Unfortunately this is the foul Common Myna, and I hope people are able persuade this species not to become further established here.

That is the lot!  It has been a hoot compiling these reports for the last 12 years and I hope it has been helpful to the readers.  As well as a report onthe area generally to COG I have also published articles in Canberra Bird Notes on the Whiskered Tern breeding event; the (re)appearance of Banded Lapwings on the Plain; and a number of articles about the Tawny Frogmouths breeding at our house.  So the area has done very well

December 2018

The month was not great for diversity with only 91 species reported,  This is the lowest total for a December since 2008 (when reports were based solely on my personal observations).

To try to get a handle on what is missing in action (MIA) I assessed the number of species in each category and how commonly species were recorded in December.

Species Missing in Action

I have used 9 broad categories to present my results.  For each category  I counted the number of species ever reported in December (158 species in total) and then the number of species recorded in December 2018.  The difference between the two values in the number of MIAs.  In the next chart I have shown the number of MIA species  and that number as a % of the total number in any December.

Of the 5 groups that are major contributors to MIA:

  • Waterbirds are expected to be missing as there was hardly any water in the area until mid-December;
  • Raptors would seem to be reacting to absence of prey due to drought; and 
  • the 3 other groups contain many insectivorous species an insects are also lacking this year (except flies and mosquitoes around our house).

Common-ness of observed species.

I counted the number of Decembers 2007 to 2017 - maximum of 11) in which each species was recorded.  This covered all 158 species seen in at least 1 December.  I then calculated the average number of Decembers for each category.  I then calculated the average restricting it to those species seen in December 2018.  An example may help to explain this:

  • For waterbirds the average number of Decembers in which species have been seen is 4.54 (many species only seen in 1 or 2 Decembers).
  • Of the waterbird species seen in December 2018, they have been seen on average in 8.08 Decembers.  Of the 11 species on the list 6 have been seen in 10 or 11 Decembers.
  • I thus conclude that it is mainly the die-hard residents that are around.
This is illustrated in the next chart.  The two groups with the highest 2018:previous indexes have red stars and the next two, blue stars.
It is noteworthy that all Honeyeater species have been seen in at least 1 December and a high proportion of them were seen in December 2018.

Unusual species

After last month’s spate of unusuals, December has been a bit more restrained.  A Brush Cuckoo in the Molonglo Valley, male and female Koels in Radcliffe and an Australian Bushlark on the Plain have been the least common species reported to me.  The Avocets and Stilts were at Foxlow Lagoon early in the month but disappeared when the lagoon reached capacity due to a downpour.  A couple of Stilts returned later in the month.

Breeding 

Quite a good haul with 15 species this month marked in red below)..  The Banded Lapwings remain, with young chicks, on the Plain doing a good job of camouflaging themselves in a muddy patch (thanks Garry for the photo).
A pair of Leaden Flycatchers were taking turns on a nest at the top of Widgiewa.

A Silvereye has a nest full of chicks on Whiskers Creek Rd.

November 2018

There are quite a few highlights in the month but I will begin with the very large flock of Masked and White-browed Woodswallows that have been feeding and engaging in some breeding activities (see below) on the Hoskinstown Plain.  I have done a detailed report here, but this is a very small proportion of the flock

There have been a number of less common species sighted this month.  Bird of the month was a female Koel reported from Knox Close on the 15th.   Photo by Sandra.
Other less common species have been an Eastern Barn Owl (Captains Flat Rd);  Whistling Kite at Wanna Wanna  Rd and Rainbow Bee-eaters (Forbes Creek).  The Avocets and Stilts at Foxlow Lagoon and the Banded Lapwings on the Plain are ongoing, having almost advanced to resident status.

Despite that list of less common species overall diversity was quite low.  We have recorded 96 species for the month which contrasts poorly with the November average of 103 species.
There seems to be a particular shortage of waterbirds (associated no doubt with the shortage of water) and raptors (plenty of road kill but I suspect little live prey).

As with last month quite a few (16, marked in red below) species have been recorded as breeding.  ‘Our’ Tawny Frogmouth family have left the nest and are exploring the area around our house. 
 The Masked and White-browed Woodswallows on the Plain are engaging in the early stages of the breeding cycle (ie copulation).  They may be nesting but the vegetation is too thick to spot the nests.  Several other species have been seen on nests.

Return migration is close to complete with about equal numbers of species on time and late.  Few species were early.  Except for Pallid Cuckoo, cuckoos in particular are thin in the air, although 5 species have been logged at least once in the month.  Migrants are highlit in orange below.

October 2018

My response to this great image of a Common Bronzewing
 by Micheáilín Ní Lochlain on the Carwoola Facebook page might be of interest/assistance to a few folk:
The best collection of bird calls is on Avibase https://goo.gl/t32sbu Unfortunately, as with the text descriptions of calls in all Field Guides, you have to know the possibles and then play the recording to compare. There is no equivalent of Shazam which takes a recording and assesses it against a database giving an ID, Also, some of the recordings for this species are pretty much the "before" section of a workshop on removing background noise!
The month has been fairly quiet overall, possibly reflecting observers being elsewhere as well as some migrants not yet turning up and of course the on-going dry weather.  90 species were recorded in total.

The Stilts and Avocets have returned to Foxlow Lagoon where there is still a surprising amount of water.  In a late look-down into the Lagoon they were accompanied by 4 Sharp-tailed Sandpipers which have rarely \been recorded in the area.  Another rarity was a Channel-billed Cuckoo, heard calling in Whiskers Creek at daybreak.

The final comment on unusual species relates to Woodswallows.  Dusky Woodswallows are quite common here but for the ;at few weeks they have been outnumbered by Masked and White-browed Woodswallows.  Even more unusually Masked Woodswallows have outnumbered the White-browed.  The biggest flock, feeding on the ground in  a paddock off PLains Road amounted to around 500 birds.

Breeding continues, including the Tawny Frogmouths at Whiskers Creek Rd.  They have again hatched 2 chicks: still at the small white fluffball stage at the time of writing.  Species noted as breeding are marked in red below.

A fair proportion of migrant species have arrived but 15 of 30 species have yet to be recorded.  3 species were early while 8 were late.  So the season is definitely not early.

September 2018


The month has been quiet overall with limited diversity. We have only managed 82 species for the month: an increase on July and August but well below the average for September of 93 species.

The major excitement has been breeding Banded Lapwings on the Plain. By mid-Month 2 birds were brooding and a 3rd pair had produced 3 chicks.  Very exciting for this broad area.  
A  Powerful Owl is still heard occasionally along Wanna  Wanna Rd, but no nest site has yet been located.  The Pied Stilts and Avocets appeared to have left Foxlow Lagoon when the site was checked from the road in September, but they were back again in early October.

Quite a few other species are breeding including ‘my' Tawny Frogmouths where the male is now incubating.  Striated Pardalotes are building nest and Magpies are nesting in several places.  Pallid Cuckoos are calling and displaying regularly.  Breeding birds have red text below.

Return migration has started with strong movements of Yellow-faced Honeyeaters in flocks of 20-30 birds moving up from the Plain on several mornings but the cool weather is keeping the insects down and thus most of the insectivorous birds have not yet appeared.  The smaller cuckoos in particular are not yet evident although the calls of Pallid Cuckoos are very evident.
Summer migrant species are highlighted in orange below.
