Recently found at the Netherlands Institute for Sea Research (NIOZ) is a ’forgotten stock’ of the rather popular report ’Laboratory Research on Sea-birds’, published in 1977 and written by Kees Swennen (in English). It is an old, but rather attractive report on interesting experiments with pelagic seabirds in captivity on Texel. Chicks of Puffins, Razorbills, Kittiwakes and Guillemots were caught under license in Scotland, raised and kept in cages until all birds reproduced successfully. Feeding experiments were the main topic of the studies, but interesting information with respect to moult and threatment is given. We found some 1200 copies in stock and instead of discarding them, we would like to send (free) them to anybody interested. Contact Theunis Piersma or Kees Camphuysen at the NIOZ.
