This is a sandalwood tree in my garden, which is embraced tightly by the Goosefoot vine. The vine is not the vegetable vampire, but it is the Sandalwood tree that is the vampire!
The roots of the Sandalwood Santalum album make contact with the host plant, here my neighbour's coconut tree, and penetrate the tissue of the host tree,s roots. Much of the nutrition is drawn this way. My neighbour, being an engineer, is unaware of this fact, and has not complained to me of the small size of the coconuts he gets from the tree!
These tiny purple flowers of the Sandalwood become dark berries, much loved by the birds. But it is the Koel, the Indian cuckoo, who has claimed territorial rights to this tree. He helps in scattering the seeds, and I find the seedlings all over my garden.
You can see the black silhouette of the koel in the tree in this picture. He does not build a nest, but his wife lays her egg stealthily in the nest of crows on the top of my tall teak tree. The crows look after the egg and the nestling after it hatches. The koel keeps a constant watch over the nest and guards it against intruders by screaming loudly. He also wakes me up every day at 2.30 in the morning!
