Population growth estimates of a threatened seabird indicate necessity for additional management following invasive predator eradications

Abstract: The eradication of invasive predators from islands is a successful technique to safeguard seabird populations, but adequate post-eradication monitoring of native species is often lacking. The Whenua Hou Diving Petrel (Pelecanoides whenuahouensis; WHDP) is a recently-described and 'Critically Endangered' seabird, restricted to Codfish Island (Whenua Hou), New Zealand. Invasive predators, considered the major threat to WHDP, were eradicated on Codfish Island in 2000. However, estimates of WHDP population size an… Show more

“…This species is a small burrow-breeding seabird considered nationally critical by the New Zealand Department of Conservation due to its low remaining population size (approx. 200 individuals) and extremely restricted breeding range (a single colony occupying 0.018 km 2 on Whenua Hou; Fischer et al, , 2018Fischer et al, , 2020Robertson et al, 2017). The WHDPs share their breeding ground with a population of common diving petrels (Pelecanoides urinatrix, hereafter CDP;.…”

“…This beach has an associated sand dune of 0.018 km 2 which is the only breeding ground for the sole remaining population of the nationally critical WHDP. There were once WHDP populations along the length of New Zealand, however the introduction of invasive mammalian pests resulted in the extirpation of all populations except the surviving ~200 individuals remaining on Whenua Hou (Taylor, 2000;Fischer et al, 2018Fischer et al, , 2020. There is also a breeding population of CDPs on Whenua Hou, with approximately 25 CDP burrows located in the same sand dunes (Fischer et al, 2020).…”
