Paul Robert Kollibay

Paul Robert Kollibay (4 July 1863 – 5 November 1919) was a German lawyer and ornithologist.

Born in Gorzów Śląski, then called Landsberg, Upper Silesia, Kollibay was the son of a district judge.

He went to the local elementary school and then the Gymnasium in Neustadt where he met Friedrich Kutter (1834–1891) who influenced his interests in birds.

His work on birds began in 1879, with studies of the species in the Prussian Province of Silesia which was published in 1906 with supplements in 1909 and later updated by Anton Reichenow.

Kollibay's collection of 3200 bird skins was purchased by the zoological museum of Breslau University but many specimens were destroyed during the Second World War.
