Hi All
Yes many migratory shorebirds have started to return but is fairly normal to be
happening at this time of the year.
Most birds arriving over the past few weeks will most likely be failed breeders
or females.
In the past days in Broome we have started seeing juvenile birds of Greater
Sand Plover, Black-tailed Godwit and Curlew Sandpipers.
Most will trickle back in over the next 6 weeks or so.
However most Oriental Plovers and Pratincole will be a bit later.
3 months seems a very short time to be away so I assume its unlikely to be the
last birds to leave and the first birds back.
Depending on the species involved they may need to stop at several places on
their way north approx 4-6 weeks then breed with an incubation of 3 weeks.
Depending on the sex and the species to what they do next but several weeks of
fattening and then head back. This would be cutting the 3 months away pretty
fine but possible.
The other option could also be that these individuals were not adults maybe 2nd
year birds that obtained breeding plumage but didnt migrate and moved to some
other place relatively close.
Who knows really? I guess the main thing is is that they are back safely after
dodging habitat loss after habitat loss to and from their breeding grounds.
Cheers Adrian
