Milvus migrans: of Forked-tail and Black-ears

Black-eared Kite

Milvus migrans lineatus

(Japanese Black Kite)

Japanese name:

Tobi

This Kite is just a little larger and bulkier than the Australian Kites.

So named for the darker patch around the ears.

It also has a more distinctive white patch just near the base of the front primary feathers

and the wings are broader.

This photo shows how the

Fork-tailed Kite

forks its tail in flight as compared to the first photo where it is stretched out squarely.

The tail looks very forked when perched. More noticeably than with the Black-eared Kites.

Notice how the wings are narrower than the Black-eared Kites below.

Here we can see yellow feet!

Usually the light is much duller for the Japanese species and colours can be difficult to compare.

It’s interesting to compare them again in different lighting conditions.

Can you tell which is which?

  2. A very interesting post, Russell. I think there are a few subspecies that winter in Malaysia but I never really got round to try and separate them.

    Really nice and informative post, Russell. We also have our local Black Kite subspecies here in Thailand as well, but it's not a big deal to distinguish from the winter visitor M.m.lineatus since it has bright yellow cere.

  5. Great photos you've got there!These Black kites, especially the Japanese one, seem somewhat lighter on the chest than the European ones.Is it a criteria for differentiation for ssp, I am not sure.I think maybe it has more to do with their diet!It is interesting to compare them: mine are coming out on the 31rst on my blog.I love the views on the mountain with it's snowy cap! What a stunning place!Cheers Russel!
