The following link provides information on the Willie Wagtail in Canberra based
on data in the Canberra Ornithologists Group database. They are certainly
present in Canberra throughout the year, but are recorded less frequently in
winter. The graphs in the data sheet show reporting rate rather than numbers of
birds. More detailed information is available in the Annual Bird Reports, also
available in the COG website. Overall there are probably about half the number
of birds present in winter as in summer, suggesting the species is a partial
migrant.

Hi Rob,
Well that's very interesting indeed.
It would be well worth having a look around your area now Rob to see if there
are any Willie Wagtails still hanging around.
Do you recall if these 2 adult Willie Wagtails that you saw in May there in
Bamaga seemed particularly large birds to you??
If they did appear like big Willie Wagtails to you, then they could be either
birds from the north of you (ie the larger race 'melaleuca' from Torres Strait
islands & PNG), or they could have been visiting migrants from southern
Australia of race 'leucophrys'.
If they just appeared about the same size as birds that you would see, say
around Cairns for instance, then they were probably likely to be of our local
northern race 'picata', which is a noticeably smaller bird than the southern
latitudinal migrants 'leucophrys' that we have been discussing here on this
thread.
What makes it hard is that all 3 races look pretty much the same, apart from
the size. I get to see our Cairns locals all year as they breed here
extensively, and they appear generally quite a bit smaller than the southern
birds that winter in the inland of Qld. I just wonder how far north these
migratory 'leucophrys' actually travel when wintering in normal non-drought
years.
But Rob, I suspect that the birds that you saw were indeed most likely visiting
southern 'leucophrys' - it is a very dry year all round & my bet is that they
get up as far as you in Bamaga in these very dry times.
Also, I've never seen a Willie Wagtail of race 'melaleuca' but from what I
read, they must appear significantly larger than our local breeding northern
birds of race 'picata', and also a bit larger than the southern birds as well.
Lots of questions need to be answered, but Lloyd & Greg are most definitely
onto something pretty significant here in having found that this species does
seem to have a major latitudinal migratory population - well, at least a fair
proportion of the nominate race 'leucophrys' anyway.
Does everyone down there in the southern Australia (say in Sydney, Melbourne, &
Adelaide), see Willie Wagtails in the months of May, June & July??
I'm just putting it out there - as they say...
cheers,
martin cachard,
trinity beach, cairns.
