Goh Juan Hui took these photographs at Turnhouse Road Park on 4th March 2013 (above). This area around Changi is where the Oriental Pied Hornbills (Anthracoceros albirostris) nest regularly LINK. An adult must have brought a fish or some other bait still attached to the hook at the end of the discarded fishing line and fed it to the chick in the nest. The hook apparently got caught in the lower mandible of the chick. It was not known what happened to the chick.
The indiscriminate disposal of used fishing lines (with or without the hooks attached) by irresponsibly fishing enthusiasts have caused a number of birds to be strangled.
In June 2009 an adult Oriental Pied Hornbill was found strangled by a discarded fishing line in a mangrove area LINK.
There was even an occasion when a White-bellied Sea-eagle swallowed a short line possibly with the hook still attached LINK.
There were appeals to fishing enthusiasts not to leave their unwanted lines indiscriminately but apparently such practice is still going on.
