The Psittirostrini were a group of special birds called Hawaiian honeycreepers. These birds used to live all over the Hawaiian Islands. They looked a bit like finches and ate mostly seeds. Their songs also sounded like other finches.
Today, only a few of these birds are still alive. These include the Laysan finch, the Nihoa finch, the Maui parrotbill, and the palila. Sadly, many others have disappeared forever. These include the koa finches, the ʻōʻū, and the Lānaʻi hookbill.

Meet the Psittirostrini Birds
This group of Hawaiian honeycreepers had many different kinds of birds. Each kind had special features, like their beaks, which helped them eat different foods. Some ate hard seeds, while others ate soft fruits or even insects.
Birds with Thick Bills
Some Psittirostrini birds had very strong, thick bills. These bills were perfect for cracking open hard seeds.
Chloridops Birds
These birds were known for their very thick bills. They were experts at eating hard seeds from plants like the Myoporum sandwicense tree.
- Chloridops kona - This bird, called the Kona grosbeak, is now extinct. It was last seen in 1894.
- Chloridops regiskongi - This was the King Kong grosbeak. We only know about it from very old bones.
- Chloridops wahi - This was the wahi grosbeak, also known only from old bones.
Birds with Unique Bills
Other birds in this group had very unusual bills, helping them find specific foods.
Dysmorodrepanis Birds
These birds had a pincer-like bill. Scientists think they might have been good at eating snails.
- Dysmorodrepanis munroi - This bird, the Lānaʻi hookbill, is now extinct. It disappeared around 1918.
Pseudonestor Birds
These birds had a bill that looked a bit like a parrot's. They used it to poke into wood to find insect larvae.
- Pseudonestor xanthophrys - This bird is the Maui parrotbill, also known as kiwikiu. It is still alive today.
Psittirostra Birds
These birds had a slightly hooked bill. They were specialists at eating the fruits of the Freycinetia arborea plant.
Xestospiza Birds
These birds had cone-shaped bills. They might have eaten insects.
- Xestospiza conica - This was the cone-billed finch, known from old bones.
- Xestospiza fastigialis - This was the ridge-billed finch, also known from old bones.
Finch-like Seed Eaters
Many Psittirostrini birds looked and acted like typical finches, eating seeds.
Loxioides Birds
These birds were very finch-like. They specialized in eating seeds from Fabales plants, which are a type of legume.
- Loxioides bailleui - This is the palila, one of the few Psittirostrini birds still alive.
- Loxioides kikuichi - This was the Kauaʻi palila. It is known from old bones and might have lived until the early 1700s.
Orthiospiza Birds
This bird had a large but weak bill. Scientists think it might have eaten soft seeds or fruits.
- Orthiospiza howarthi - This was the highland finch, known from old bones.
Rhodacanthis Birds
These birds had large bills and were also seed-eaters, especially liking legumes.
- Rhodacanthis flaviceps - This was the Lesser koa finch, which became extinct in 1891.
- Rhodacanthis forfex - This was the Scissor-billed koa finch, known from old bones.
- Rhodacanthis litotes - This was the Primitive koa finch, known from old bones.
- Rhodacanthis palmeri - This was the Greater koa finch, which became extinct in 1896.
Telespiza Birds
These birds were also finch-like and ate seeds. They were also known to be opportunistic scavengers, meaning they would eat whatever they could find.
- Telespiza cantans - This is the Laysan finch, which is still alive today.
- Telespiza persecutrix - This was the Kauaʻi finch, known from old bones.
- Telespiza ultima - This is the Nihoa finch, another species still alive.
- Telespiza ypsilon - This was the Maui Nui finch, known from old bones.
Why Did Some Disappear?
Many of these amazing birds became extinct, meaning they are no longer found anywhere on Earth. This often happened because their homes were destroyed, or new animals like rats and cats were brought to the islands. These new animals hunted the birds or ate their eggs.
