harrier @ kranji marshes - 19Nov2016

At first, I thought a brahminy kite was flying low over the marsh but soon realised that this was not a kite but a harrier.... likely a juvenile eastern marsh harrier. The head of the harrier was very visibly pale and the rest of its plumage was in much darker tones of brown with a distinct white rump.

It made several passes over the marsh before flying off towards the north.

Horseshoe crabs-rescued@Kranji 12Mar2011

This hapless pair were trapped in a small section of fish net probably carelessly abandoned by a fishing enthusiast without much thought about what the abandoned net will carry on killing.

The smaller male was easy to remove but the large female below was well and truly entangled by the net. A few strategic pulls and careful picking soon released the female. Both went on their separate ways free. Hopefully they do not get entangled by other nets or entangling material.

Local fishermen must pay more attention to where they dispose of their nets.

Spiked Horseshoe Crab @ Kranji 12Mar2011

Came across this spiked Horseshoe crab at the shore near Carpark A. It was lying upside down and did not seem very bothered or in a hurry to right itself up. There were some other horseshoe crabs in an inverted position as well and perhaps this was a bevahioural trait for these crabs to be in an upturned position. (??)

This particular crab had a forked tail with the extra spike on the anterior part of the main tail pointing upwards about a third of the way from the base of the tail. The cross-section of the main tail was also not symmetrical perhaps to accommodate the extra spike and the combined length of both the shorter main tail as well as the spike seemed to correspond proportionally to the single tails of the other Horseshoe crabs.

Siva suggested that the spike mutation could be due to pollution in the Johore Straits. We did not see any other unusual tails whilst on the shore.
