Life around a rotting tree trunk 2: Collared Kingfisher

A pair of Collared Kingfishers (Todiramphus chloris) was nesting in a cavity found at the central point of a rotting tree trunk in a small piece of secondary growth at Eng Neo. Most of March 2006 the birds were flying in and out of the nest. Sometimes the arrival would be accompanied by the shrill cries of the bird. At other times the bird would fly in silently.

The hungry nestlings needed to be fed regularly and the parents worked hard bringing them food. There would always be some invertebrates like a centipede or a grasshopper. The birds would stop over at a nearby tree, checking to see whether it was safe to proceed, before flying to the nest. Initially, it entered the cavity to pass on the food but later it just stopped at the entrance. Sometimes both parent birds approached the cavity at the same time. In such cases one would veer off and wait its turn. There had also been a few cases when the morsel brought to the nest was not accepted by the nestlings (see above). In such cases the parent bird flew off to a nearby perch to consume it.

At the upper end of the trunk was another cavity. Here, a pair of Long-tailed Parakeets (Psittacula longicauda) initially took occupancy. The presence of the parakeets nesting above caused no problems to the kingfishers. Both species coexisted peacefully. However, when the hornbills were around the rotting trunk, which was not often, the kingfishers as well as the parakeets were invariably frightened away.

    I have been observing a pair of
    nesting collared kingfisher at
    Kuala Juru, mainland Penang, for
    nearly everyday from feeding
    until fledging. (Time to fledge
    about minimum 18 days-not certain exact date eggs were laid)
    A few times the parents will fly
    away from the nest(hole on laterite
    "cliff" about 10ft high)with food
    still in their beak but everytime
    they will return to feed the chicks. There could be 3 reasons
    why they flew away with food,
    1) The parents were disturb
    2) It takes too long to feed, food
    too big, not dead enough,etc
    safety reasons it will back away
    3) One of the chick is already too
    full and will refuse food, it
    will fly back to feed another
    chick.

    Sometimes it will drop its food
    flying towards the nest or away
    from the nest but it will pick it
    up and feed the chicks.

    The 2 chicks fledged about a week
    ago and the parents are still
    feeding them at the mangroves
    at the river mouth of Sg. Juru.

    I was lucky enough to observe
    another family of already fledged
    collared KF (with 3 chicks) about
    100 metres away, and the parents
    continue to feed them for at least
    another 2 weeks.
