Wreathed Hornbill male

Last month while at Tabin Wildlife Reserve I saw this male Wreathed Hornbill Rhyticeros undulatus steadily feeding his sealed-in female partner on this huge “Mengaris” Koompassia excelsa tree.  I estimated that the nest-hole would be about 40m above the ground.  I believed this is still the incubation period and the male has a huge effort ahead to feed both the female and the coming chick. Studies done in Thailand have indicated that the Wreathed Hornbill would have a feeding range of up to 10 km2 during this breeding season.  On Mount Kinabalu I have seen this hornbill in flight near the mountain huts at around 3,200m.  More power to you, Mr Hornbill.
