Another really rare migrating bird dies in Singapore. This Eyebrowed Thrush (Turdus obscurus) breeds in the coniferous forests east of Siberia and migrates huge distances to Southeast Asia during the winter months, although not all of them successfully complete their journey.
Siberian Thrush (Geokichla sibirica) at Kent Ridge campus
Location, date and time: Singapore Island, Kent Ridge campus, building S4 off Science Drive 4; 11 November 2013; 0936 hrs.
Observation: A female, about 20 cm in head and body length, was discovered freshly dead on a verandah.
Remarks: The bird was presumably killed after having flown into a glass window panel along the verandah. The fresh carcass was collected and deposited in the Lee Kong Chian Natural History Museum at the National University of Singapore.
The Siberian Thrush breeds in Siberia, northeast China, Korea and Japan, and winters in Southeast Asia. It is considered an uncommon migrant in Singapore, showing up mainly in November and early December enroute to Sumatra. This species seems to be dependent on forest cover in its wintering grounds (Yong et al., 2013: 137).

Two birds die from crashing into windows at NUS Science today
By N. Sivasothi, 13th November 2013;
It is very sad to see a bird die because it crashed into a window, thinking it was flying into the sky. This has been happening for years, and we are likely to see more cases as more buildings are built, with shiny reflective surfaces and as we install more glass windows.
A bird with its fragile, light skull flies for the reflected sky or trees at high speeds and instead strikes a window and is killed.
This is all the more tragic when a northern-winter migrant like the Blue-winged Pitta (Pitta moluccensis), having survived the long journey south from Myanmar or Thailand, dies in Singapore from a window strike.
Several dead Blue-winged Pittas have tragically been reported in the last month in Singapore. This afternoon, we learnt that even our corridor window, in the present configuration of our landscape, is creating such a mirage. A Blue-winged Pitta crashed with enough force to scratch the window.
