Wildlife Spotting

These look like Green Pigeon fledglings. You need to check the Treron sp. which occur in your area

There was a bug which caused some peoples maps to disappear after saving but yours now works after you saved again. I looked into the possibility of Cormorants in Singapore as there was no record of them there prior to 1990s. It appears they were introduced to the Jurong Bird Park and Mandai Zoo as free-flying exhibits and have since been reported from Tuas and Changi amongst other places. If they are Cormorants it is likely where they came from, so they would be termed as Escapes or Introduced. It may be worth checking with the Singapore Birding organisations for more information. By the way, your sighting location is close to where I used to live in Jln Jelita.

For some reason your map is not showing on this page and you have nothing in the Habitat field about the habitat where you saw it, there are condo's everywhere so that is too vague. I think these are more likely young Cormorants but habitat and precise location details would greatly assist.
