@ Raheema, I think Radar is the main tool to track the flight behavior of migratory birds. It is also now possible to manufacture a small GPS device that is solar charged, so you don't need to change batteries and use it to track flight patterns of birds.

Devin R de Zwaan

It really depends on the scale of your question.

If you are interested in individual migration, then tracking technology like light level geolocators or GPS tags are ideal depending on the body mass of your focal species. Check out these papers for some resources:

Article Light‐Level Geolocator Analyses: A user's guide

Article Ten years tracking the migrations of small landbirds: Lesson...

If you are interested in populations or multiple populations, radio telemetry arrays such as MOTUS can be very useful if there is the available radio tower infrastructure already set up. Pooling information from studies on individuals (geolocators, GPS) is also a good approach and we are starting to see more and more of these large collaborations that are really advancing our understanding of bird migration. Some examples of both:

Article A range-wide domino effect and resetting of the annual cycle...

Lastly, if you are interested in larger community-wide scales then there are some great advancements in using weather radar systems to track mass movement of birds. Some examples:

Hope this helps!

Good question, I have a friend who was studying migratory birds and has never published the data. GPS tags maybe on a particular number of birds on a particular number of migratory bird species.

I normally follow the migratory birds during the harvest season of maize in Kenya. So we use the time of harvest to follow the migration of birds.
