Crowned Hornbills are very seasonal visitors to our garden. We generally hear their somewhat melancholy whistles in the vicinity long before actually seeing them as they fly from one tree to the next in our garden. They are difficult to spot for they tend to forage among the foliage in the tree canopies and only linger for a day or two before moving off. About six of them have been seen over the past ten days or so and have now disappeared. What makes them distinctive is their dark orange-red bills with a casque on the upper mandible.
I hope we will see them again before the end of winter.
