Broadbills make up a small group of tropical birds of the family Eurylamidae. There are a total of 15 species, mostly brightly coloured. Eleven species are from Southeast Asia while the remaining four are African species. The Thai-Malay Peninsula claims seven species.
Singapore used to have five species: Black-and-red (Cymbirhynchus macrorhynchos) (above left), Black-and-yellow (Eurylaimus ochromalus) (above right), Banded (Eurylaimus javanicus) (below left), Dusky (Corydon sumatranus) (below right) and Green (Calyptomena viridis) (top). They are all extinct now.
Peninsular Malaysia and Thailand still have seven species, the five above as well as Long-tailed (Psarisomus dalhousiae) (below left) and Silver-breasted (Serilophus lunatus) (below right).
Broadbills are so-called because they have a large, broad, flat, hooked bill and a wide gape. All the seven species are found in rainforests. They are more often heard than seen. And all are distinctly brightly coloured – and cute.

I may be completely wrong here but are the 5 species of Broadbills “extirpated” and not “extinct” since they are still found elsewhere? I am not sure the correct term (since I am not a scientist 🙂
Either way, that stinks that 5 are gone from Singapore. Is there any possibility of reintroduction or is that too difficult with this family of birds?
Extinct is usually associated with species. I must confess I am not too familiar with the word extirpated.
Now that the relevant government agencies have completed their task of turning the country into a “city in a garden” I am sure we can persuade them to look seriously into the reintroduction of bird species.
Habitat loss is the main reason why we lost five species of broadbills, as with most extinctions all over the world. So far, I am aware of only the reintroduction of the Oriental Magpie Robin, whose population used to be excessively poached. Also, we have been successful in increasing the population of the Oriental Pied Hornbill.
Reintroducing broadbills sounds exciting. We need to study their habitat, food and other needs. Mostly, we need committed birders and ornithologists who are interested in the project.
Thanks for the suggestion.
Birdfreak, you are correct. Extinction refers to the complete loss of a species, none are alive, anywhere. Extirpation is the local extinction of a population, not a species. The Singapore populations of those broadbill species are extirpated. You caused a bit of momentary panic in my mind by saying they’re extinct – they’re absolutely beautiful birds and I don’t want to see them go. Great pictures by the way.
Yes, you are both right. Local extinction is extirpation. Thanks and noted.
