Research by the Zoological Society of London found that over 4,000 years ago, tropical Pacific Islands experienced a catastrophic mass extinction of birds, with around 1,300 species disappearing. The loss was largely due to overhunting and deforestation caused by human arrival.
A study by Dr. David Lohman suggests the Philippines could have more unique bird species due to its high biodiversity and geographic isolation. This could have significant implications for conservation efforts in the country.
A new study reveals that giant noctule bats feed on songbirds during nocturnal migrations, contradicting earlier suggestions that they only eat insects. The researchers used stable isotopes to track the bats' diet and found a significant presence of songbird flesh in their stomachs during autumn.
Research suggests that pigment spots on bird eggs strengthen the shell by compensating for reduced thickness caused by calcium deficiency. Females nesting on low-calcium soils lay thinner-shelled, more-spotted eggs than those on high-calcium soils.
