Challenges and benefits of using unstructured citizen science data to estimate seasonal timing of bird migration across large scales. [PDF]

open access: yesPLoS ONE, 2021
Millions of bird observations have been entered on online portals in the past 20 years either as checklists or arbitrary individual entries. While several hundred publications have been written on a variety of topics based on bird checklists worldwide ...

Climate change could overturn bird migration: Transarctic flights and high-latitude residency in a sea ice free Arctic. [PDF]

open access: yesSci Rep, 2019
Climate models predict that by 2050 the Arctic Ocean will be sea ice free each summer. Removing this barrier between the Atlantic and the Pacific will modify a wide range of ecological processes, including bird migration.

Associations of Synoptic Weather Conditions With Nocturnal Bird Migration Over the North Sea

open access: yesFrontiers in Ecology and Evolution, 2020
The southern North Sea is part of an important flyway for nocturnal bird migration, but is also risky as it stretches over a large surface of water. Selecting nights with suitable weather conditions for migration can be critical for a bird’s survival ...

The Influence of Winter and Spring Large-Scale Climate Patterns on the Timing of Male and Female Blackcap Spring Passage at the Baltic Coast [PDF]

open access: yesBiology
Sex-specific adjustments of bird migration phenology to climate change are understudied. We analysed blackcap migration timing using spring (26 March–16 May) ringing data from Bukowo–Kopań (N Poland) in 1982–2025. We assessed the influence of large-scale

Field validation of radar systems for monitoring bird migration

open access: yesJournal of Applied Ecology, 2018
Advances in information technology are increasing the use of radar as a tool to investigate and monitor bird migration movements. We set up a field campaign to compare and validate outputs from different radar systems.

Altitudinal migration behavior patterns of birds on the eastern slope of Mt. Gongga, China

open access: yesAvian Research, 2023
Many bird species in montane regions exhibit altitudinal migration behavior; however, altitudinal migration of birds is still understudied, especially in Asia. Mt. Gongga (7556 ​m) is the highest peak of the Hengduan Mountains in Southwest China.

Shifts in Bird Migration Timing in North American Long-Distance and Short-Distance Migrants Are Associated with Climate Change

open access: yesInternational Journal of Zoology, 2017
Bird migration is a synchronized event that has evolved over thousands of years. Changing temperatures due to climate change threaten the intricacies of migration timing for birds; however, the extent of these changes has only recently begun to be ...
