Marsh Hawk-Eagle?

OLYMPUS DIGITAL CAMERA

Can you see the head of the Changeable Hawk-eagle popping out above the water hyacinths.

We are used to seeing Marsh Harriers flying low over marshes and open grasslands looking for food. But earlier this week we saw a dark morphed Changeable Hawk Eagle, Nisaetus cirrhatus, diving into a pond at the Kranji Marshes. The pond was covered by water hyacinths which would have look like dry land from above. It disappeared from view for some minutes. We thought that it may be in trouble  having mistaken the hyacinth carpet for a hard surface.

We were relieved to see it jumped up and not stuck in the mud.

Finally it popped its head up above the water hyacinths and start flapping its wings. We were not sure if it was stuck in the soft mud at the bottom struggling to get out or looking for food among the water weeds.

Finally to our relief it jumped up and flew low over the surface of the pond. It then scoop down again as if to pick out something before flying off to a Rain Tree near by.

It is hard to tell even from this zoom image what it is in its talons.

This frame showed that it had caught something. Does it looked like a small terrapin? It must have dropped it as there was nothing in its talons in the next frame. This is very possible as it cannot sink its talons into the harder shell of the terrapin.

We think that it may have dropped whatever it caught as there is nothing in its talons.

The open Albizia and Scrubland behind the marshes have been cleared for agricultural farms. It may be that the Hawk-eagles main preys like changeble lizards, small mammals are gone. Are they now changing to aquatic animals to survive? Further observations will be needed to see if this is true.
