Margaret Bushby Lascelles Cockburn

Margaret Bushby Lascelles Cockburn (2 July 1829 – 26 March 1928) was an artist and amateur ornithologist who lived in the Nilgiris in Tamil Nadu, India.

The family initially visited Kotagiri in summer but settled permanently around 1855 at "Hope Park".

Cockburn experimented on tea planting at Alports Estate and made numerous observations on local natural history and many of these were reported in the works of Allan Octavian Hume.

The Natural History Museum, London, produced a diary in 2002 with illustrations made by her of the fauna and flora of the Kotagiri region.

She died on 26 March 1929.A subspecies of Anthus similis from the Nilgiri region was named after her, but this is no longer considered valid.
