April Showers- Birds and Fish and Cetaceans & Feathers?

April Showers- Birds and Fish and Cetaceans & Feathers?

Farmers were delighted with rain that fell most days during this first week of April. I can’t say that it’s been easy to show people the birds during this very wet time, although afternoons were generally better and we managed to see quite a lot of avian migrants that had come in from Africa.

Montagus Harrier adm 6227
This young male Montagu’s Harrier shows all adult plumage. He has quite a dark grey hood and bolder streaking on the underwing coverts as well as on the belly and flanks which are tyical of a younger male.

Montagus Harrier subad m 8496
The slimmer winged Montagu’s Harrier sweeps past us. This is a transitional male showing a mix of adult and juvenile plumage. In time he’ll moult all the brown shown here on the upper coverts and the rest of the flight feathers which will be replaced gradually by new grey feathers

White headed Duck m 5635
White-headed Duck – the underlying feature with the blue bill seems to show where the colour is a consequence the reflection of blue wavelengths by a colourless superficial layer with absorption of all other wave-lengths of incident light by a deeper black layer containing large amounts of melanin. Some studies have been done on Ruddy Ducks, a very similar ‘stifftail’ species and show that the blue bill colour is a physical, structural phenomenon and not due to the accumulation of a specific blue pigment.’
