White-throated Needletails

[Michael Tarburton <>]

G’day

Thanks Stephen for sharing todays observation - much appreciated.  Margaret 
Windeyer also saw 2 WTNT 4 days ago between Coonabarabran & Gunnedah.

Some observers presume they overwinter and others believe some migrate much 
later than most birds.  If they are pre-breeders it probably does not matter.  
It is presumed they are like Common Swifts & that they will not breed until 
they are 4-6 years old.  In some years none are reported through winter in 
Australia, but in other years 5-10 observations may be made.

Have fun looking for these interesting birds.

Cheers

Mike
