These bird was
found and photographed near Hidd, Bahrain August 4 - 6th 2005 by local

The
site in question is a small reed lined pond, amonst the extensive
coastal land reclaimation that is the newly created Hidd Industrial
area.
The pond is currently one of only a few places in the area that
provides a
summer supply of
fresh or brackish water. However it is also situated near a large pig
iron smelter
that belches out prodegous quantaties of ferrous oxide dust, the
pond itself is not polluted and has a healthy resident population of
birds but it also attracts birds resident in the smelter to drink.
It is now
thought that the color of these individuals is as a consequence of that
pollution.
Just how the birds are contaminated, be it through the food chain, in
dust baths, in a water souce, is not known but it has added a flash of
color to two of the most commonly seen species in Bahrain. We would be
interested to know from anyone how the health of the birds might be
affected. It is known that iron dust in a marine environment can be
benificial to the food chain.
