Not a Red Commodore

Read on to explain that!  A happier blog today!

There was fog in Canberra early today ...
and a strange effect of the shadow of Mount Ainslie as the sun rose.
However when 17 COG members and guests gathered in the car park at the Tidbinbilla Nature Reserve Visitors Centre there were clear and pleasantly cool (~3oC) conditions. 

A range of the usual suspects were seen before we moved off towards the Time Trail in search of Robins. 
As usual a number of folk were caught out by the beeps emanating from the Ranging device.  
This is a Doppler Acoustic Sounder.  Thanks to my friend Sandra I now know that
A Doppler Acoustic Sounder is an instrument for measuring wind speed. The one at Tidbinbilla is a multi-axis system, with the three antennae pointing in different directions (one vertical, two at angles), and each serves to transmit and receive the sound signals, giving very precise wind speed measurements.
It sounded very like a Grey Butcherbird!  Moving on from that, the expected Flame Robins appeared.  As they were actively feeding counting was a little challenging but 10 was recorded as the total, evenly split between males 
and females.  A male Scarlet Robin was also seen at this time, and another pair of the species close to the end of the outing. 

An Emu was grazing in the paddock and added to the checklist. 

Passing through some denser vegetation added 3 Eastern Yellow Robins to our tally of members of the family Petroicidae.  The hoped-for 4th species (Hooded Robin) did not manifest itself.  Several other species, including a Speckled Warbler were recorded here.  The leader took folk on a scenic route with lotsa rox!
Fortunately we got back to the proper walking track and thence to the dirt road back towards the Visitors Centre.

As we headed back across the paddocks, getting a close look at a/the Emu
.... our first (and only) raptor for the day appeared, coming up from a low level and soaring in the middle distance.  With longs wings held level in flight and a uniform brown colour it was identified as a Black Falcon (and thus the opposite of the official WW joke about not a Grey Falcon, but a Silver Commodaore): a lifer for some of the group and an addition to others’ ACT life lists.  Here is my photo ...

 .. and one of several by Ryu.
Getting close to the VC a pair of Scarlet Robins and several (~22) Yellow-rumped thornbills were spotted.
All up we recorded 32 species, with a full list at https://ebird.org/view/checklist/S57500168

A tour of the West (part 1)

Image
A friend from my time in the UN sent me some photos of her family trip along Route 66.  They did this is a large camperwagon rather than a Chevy Corvette (apparently the kids jacked up about being offered a trip in the trunk).  It seems to have been a very good trip for them and most interesting to see their photos.  It was also educational for me, as I found out the German for rocking chair (schaukelstuhl, since you ask). They did 7200 miles in 30 days - a pretty serious bit of distance. This made me think of the trips we did in 1981 when living in Denver.  Frances initiated that idea by getting a book about the National Parks of the West  and marking interesting places.  I then worked out a route on a Rand-McNally Road Atlas (GPS was unknown then  - as were iPhones, personal computers and the internet).  From memory, taking nearly the whole Summer school holidays we covered about 10,000 miles in 70 days.  Here, approximately,  are our routes: That map comes from Google Maps (G

Insects from pine trees

Image
This afternoon (13/1/2015) we were looking out of our sunroom and noticed a strange bit of mist.  On getting my binoculars on the case I found it to be a cloud of tens of thousand of insects.  They appeared with naked eye to be flying away, but with binoculars I thought they were circling. Here are some images In the second one it may be possible to see there are two streams coming from the top of each tree. There was a loud buzzing noise but that could just be several thousand wings. Earlier in the day Frances had been to some nearby willows and they were infested with many little black soft bodied insects.  Perhaps they shifted to the pines and were swarming? Help!! Any information welcome. A colleague, from Wamboin, had noticed a similat phenomenon, but involvng eucalypts rather than pines!  Here are the photos he took with his phone. I have consulted some expert friends.   Their responses were: I would have gone for chironomids. I recall years ago driving al

Satin Bowerbird gets ready for Lanigans Ball.

Image
Having some time to spare today I went to check the bower near "Tom Green's Seat" in the Australian National Botanic Gardens.  The bower was well occupied by what I take to be - based on the green plumage and yellow bill - a 5th or 6th year male Satin Bowerbird.  (With all these images, click on them for a bigger - unfortunately not better focused picture.  The shots were taken hand held on full zoom from about 10m distance into a fairly well shaded location.) He was very much engaged in adding to the construction. Then it seemed that another bird called from the bush above.  This led to a whole lot of activity: the most spectacular (and worst imaged) was a flash of the wings: The bird also did a fair bit of hopping around.  Given that it was still immature I called to mind the greatest traditional Irish song of all time: Diarmuid O'Leary and the Bards performing Lanigan's Ball .  This ditty refers to spending "6 long months at Brooks Academy learning
