Asian Koel – Aggression or Duetting?

Little Heron – social behaviour
“Little Herons (Butorides striata) have become increasingly common in the urban neighbourhood. I estimate 3-4 adults in a 1.5 km radius. We see them almost daily on the electric wires, commonly at dawn and dusk.

Common Greenshanks’ aggressive behaviour
William Ip is sharing his images of waders that he photographed in Nam San Wai, Hong Kong, somewhere near the Wetland Park sometime last year. Field ornithologist Wang Luan Keng thought the above pair of birds to be Spotted Redshanks (Tringa erythropus) and suggested that David Li of Singapore’s Sungei Buloh Wetland Reserve should be consulted as he is among the best in shorebird identification. Well, David confirmed Luan’s ID.
David also identified the Common... Read More

Less House Crows… more Asian Koels…
The Asian Koel (Eudynamys scolopacea) is a brood parasite that sneaks into the nests of House Crow (Corvus splendens) to lay her eggs (above). The bird is a resident species but during the northern winter months, the local population is supplemented by migratory species. It has a sharp, shrill call LINK that some locals find irritating – especially when made during the early hours of the morning.
The number of koels in Singapore has been increasing slowly through the... Read More

AGGRESSIVE BEHAVIOUR OF STRIATED HERON: Fight, Flight or Fright?
“On the 24th July 2012, I was observing the fishing antics of Striated Herons (Butorides striatus) along the concrete banks of Rochor Canal, where they were seeking out fish prey at the water’s edge with unwavering concentration (above).
“At one particular inlet to the canal, there appeared to be a relatively higher concentration of fish, where the water was shallow and clear – definitely a choice fishing spot from any heron’s perspective. It was at this... Read More
