Ornithological Notes

‘Ornithological Notes’ is a series of avian natural history notes submitted by various experts. Many of these notes provided research and analysis of vocal differences in birds that supported taxonomic decision-making. Others touched on a broad array of life history topics.

Starting in 2012 and continuing through 2018, 454 Ornithological Notes were published in the precursor to Birds of the World, HBW Alive. They are now available here, including their original references, media links, supporting PDF documents, and recommended citations; we have also generated DOI links for each note.

They can be accessed two ways:

1) Search the full list of published notes provided below.
2) Access them from within a species account, where they are present, by clicking the associated “Ornithological Note” link.

These notes add important nuance and insights to each species they cover. Eventually, we hope to develop a more robust way to search the Notes and potentially continue the series.
