Data from: Interspecific competition promotes habitat and morphological divergence in a secondary contact zone between two hybridizing songbirds

- 摘要：
- and looked for associations between habitat use and bill morphology, which have been previously shown to be more divergent in sympatry than in allopatry
Data from: A test of a corollary of Allen’s rule suggests a role for population density

- 摘要：
- environments, bill surface area increases with temperature. Increases in both population density and sexual dimorphism, however, could also explain increases

- and processing, i.e. bill size. In fact, this is the natural history basis of major discoveries on adaptative evolution in the face of changing food resources
Data from: Multiple reversals of bill length over 1.7 million years in a Hawaiian bird lineage

- 摘要：
- of sequential reversals in bill length. We document three single and two multiple reversals of bill length on six main islands from oldest to youngest, consistent
Data from: Functional and evolutionary consequences of cranial fenestration in birds
- 负责人：
- DOI：

- 摘要：
- . The main anatomical differences between the two taxa are in the crania. Palaeognaths lack an element in the bill called the lateral bar that is present
