Which bird thermals the best?

So in a recent conversation with a greatly experienced soaring pilot,
I was told that Buzzard's have terrible thermaling skills. I tend to
agree with this as it sure seems Buzzards don't get into the core and
stay there. The lesson learned was don't let Turkey Buzzard show you
where the core is, just let them lead you to the thermal.

I thought it would be interesting to ask you good people if anyone has
any knowledge on these issues. *Does anyone know which broad winged
birds have better or worse centering techniques that you can use to
your advantage?

White Storks. Although they can only fly about 30 miles on the flap,
they migrate 6000 miles on thermals. Due to the short flap range,
those that choose there wrong path over the Sea of Marmara drown
there. I've seen an estimated 1,500 in a thermal in Turkey.
Impressive glide also.
