Glossy Ibis
Plegadis falcinellus (Linnaeus, 1766)
IB
GLOIB
1360
Family: Pelecaniformes > Threskiornithidae
This rather smart bird, with its glossy green and purple-brown plumage, is not much bigger than a Curlew, something that surprises many encountering the species for the first time.
The Glossy Ibis has become more familiar to birdwatchers following a series of mass arrivals in the 2000s. Increasing numbers of reports since then mirror an increase in the breeding population located in the south-west of Europe. There have been a number of breeding attempts here, and it is likely that more regular breeding will be a feature in the future.
Climate change is thought to have supported the growth in visiting Glossy Ibis to Britain, with milder winters aiding their survival and enabling individuals to attempt breeding attempts the following year.
