Migrations question (1 Viewer)

I am is amateur birder and i have question, when time birds migrate?

Not so easy to give a simple answer to that question. Different species migrate at different times of year. For example migrants to Europe mostly move north around April/May returning to their winter quarters, mostly in Africa around August-September.

As far as Indonesia is concerned you will see some northern breeders from Siberia arriving in Java around October and departing around March. I believe that there is also migration between Australia and Indonesia.

I have seen Oriental Honey Buzzards crossing in huge numbers from Sumatera to Malaysia at the beginning of March on their way north to their breeding grounds.

This is a very complex subject however...

Are you in Java or one of the other islands?

To add what bittern said.Different species will have different migrating season.The Perliarctic migrants from Europe and asia are migrants in East Africa and Africa in general during the winter season in the North.In Africa we also have Intra African migrants,which are more common with in africa,apparently different intra African migrants migrate internally in different times.We also have rain migrants in Africa,and these are more common from high altitude areas to low altitude areas during the rainy season.
Anyone with a good version of Nearctic migrants?Am not so sure on them.

Nicky,

The Nearctic migrations are very similar to those between Northern Europe and Africa except that the Nearctic migrants are mostly wintering in Central or South America. Times of year for their migration are much the same as those between Europe and Africa. They do have an advantage though as they don't have to cross such a major barrier as the Sahara.

Mike,
Thanks alot for the info.Its wonderful how the B/f is quite a resource,its quite an encyclopedia.
Back to migration.We are beginning to see the migrants in Africa even before the winter in North,its mostly with the birds that over stayed in our region and they are now gaining their winter plumage.I do bird ringing every Thursday morning in Nairobi and we were lucky today to have a willow warbler,it lacked fat on the breast hence no fat score.Hope some one in Europe will recapture the same bird to prove that we don't have resident Willows in East Africa.
By the way how can you tell the different between sexes in warblers [willow]?

Nicky!
