Parrotfish are named for their dentition, [5] which is distinct from other fish, including other labrids.Their numerous teeth are arranged in a tightly packed mosaic on the external surface of their jaw bones, forming a parrot-like beak with which they rasp algae from coral and other rocky substrates [6] (which contributes to the process of bioerosion).
A large collection of sketches and studies for Parrots are included in the major Lear art collection held at the Harvard University Houghton Library. [55] In 2018, a copy of Parrots was sold at auction by Bonhams for £90,000, [56] and in 2020 another copy was listed by Christie's with a guide price of £40,000–60,000, and fetched £60,000. [29]
An alternate theory to the dinosaurian origin of birds, espoused by a few scientists, notably Larry Martin and Alan Feduccia, states that birds (including maniraptoran "dinosaurs") evolved from early archosaurs like Longisquama. [9] This theory is contested by most other paleontologists and experts in feather development and evolution. [10]
A potential answer is that Southern California cities have only in the last 100 years provided these sister species with a resource untapped by native birds: the fruits and flowers of exotic trees ...

A turning point came in the early twentieth century with the writings of Gerhard Heilmann of Denmark.An artist by trade, Heilmann had a scholarly interest in birds and from 1913 to 1916, expanding on earlier work by Othenio Abel, [12] published the results of his research in several parts, dealing with the anatomy, embryology, behavior, paleontology, and evolution of birds.
