So, wind turbines again, maybe, but no clear evidence as yet.

Thanks Anthony, I did recall a paper that Mike did for the Birdlife Australia magazine a numbers of years ago which summarised some of the reasons
for its decline that Philip mentioned, but I can’t readily locate it. However, the following link to an Australian Field Ornithology (https://afo.birdlife.org.au/afo/index.php/afo/article/view/2228)
paper titled “Recent increase in knowledge about numbers and flight behaviour in the White-throated Needletail Hirundapus
caudacutus” could be useful, Birdlife Australia members will be able to download the pdf version for free. Jack Holland

There is a fellow called Mike Tarburton who monitors all swift records and releases a short report each year. He presented to COG in 2015. Google his details or see the birding-aus chatline archive.
Many years ago, I remember seeing a flock of around 400 needletails over the Pine Ridge property in west Belconnen (before the grape vines went in). Most were hunting insects less than 15 metres off the ground. The noise was incredible.
A few years later I picked up this road-killed specimen on Coulter Drive:

Lovely. John Gould could write very nicely. I am touched by his describing the sky as being peopled with birds. 'Peopled' was a common usage in past times of course and was used to describe all sorts of things - but its still a charming
way to describe what others may have simply called a flock.

Wow... that makes sense... cheers Philip
About that question. Could be many reasons but most likely suggestion is reduction in insect prey in northern Asia (maybe in Australia too) or in places along their migration routes.
Hard to dispute an actual actual decrease in population numbers because in past decades I (and most people), would encounter flocks of sometimes up to hundreds of these birds, several times a year and sometimes several days in succession at any one place,
through the summer. This would be in all places I lived in from around Melbourne to Brisbane. Rarely encountered like that in recent years and it has been a gradual decline. I would not think their distribution has changed at all, though I could be wrong on
that.

Cheers Kim,
Wonder why their numbers are dwindling... also, could it be an actual decrease in population numbers or a shift in their distribution/range (yes possibly both). Were high numbers typical 10+ years ago?

Yes, they often soar in ahead of cloud banks, weather changes and thunderstorms but are also sometimes seen in clear skies. But there is no predicting when or where you will see them. Sometimes they may zoom in not far above your head - I have heard the
swoosh of their wings. But more often they are higher than that. A couple of times I have been looking at a soaring raptor and realised there were Needletails up there too. Becoming rare now, though flocks of many 100s used to be quite common. Last time
I saw a flock of that size was around 2012 down at Shoalhaven Heads

Needletail maybe? (AKA swifts). Two species locally. As shown in relevant books. Outside, up in the sky, at whatever altitude, at almost any location. Most of my Canberra observations
have been when hanging out or taking in washing on the hills hoist. In Australia mostly in summer to early autumn. Probably most often in late afternoons and often before rains, although why that is the case must be a bit of a mystery. .

Dies anyone have some refined hints and tips for needlepoint observations? Locating, timing sighting etc?
