Automated Bird Counting with Deep Learning for Regional Bird Distribution Mapping

Animals, 2020
Simple Summary To detect changes in migrating bird populations that are usually gradual, regular counts of the flocks should be carried out. This is vital for giving more precise management decisions and taking preventive actions when necessary ...

Dense sampling of bird diversity increases power of comparative genomics

Nature, 2020
Whole-genome sequencing projects are increasingly populating the tree of life and characterizing biodiversity1–4. Sparse taxon sampling has previously been proposed to confound phylogenetic inference5, and captures only a fraction of the genomic ...

Structural absorption by barbule microstructures of super black bird of paradise feathers

Nature Communications, 2018
Many studies have shown how pigments and internal nanostructures generate color in nature. External surface structures can also influence appearance, such as by causing multiple scattering of light (structural absorption) to produce a velvety, super ...

Spatial ecology of little egret (Egretta garzetta) in Hong Kong uncovers preference for commercial fishponds [PDF]

PeerJ, 2020
Many natural wetlands have been converted to human-influenced wetlands. In some instances, human-influenced wetlands could provide complementary habitats for waterbirds, compensating for the loss of natural wetlands.
