One of the most important contributions has been from German Jens Hering. See my blog's tab on research for a flavour of what he has achieved.

Jens is currently in Libya again (for two weeks) and is mostly visiting the south. A map below shows some of the places he is visiting. These are Ghadamis. Jaghbub, as Sarir, Kufra and Uweinat.
I am very excited about what he might find and I understand he is armed with very advanced optics.
Jens realised before I did that the government project farms in the desert (and in the north) have altered the landscape of wintering birds and some migrations.

I know Jens publishes through scientific journals so we may have to wait a few months before we know his results. I will find that wait difficult!
