Migration strategies within the tropics are still poorly understood as are the drivers of movement and the degree of connectivity between sites in migrant birds that have their global range and life cycle exclusively on a single continent – intra-continental migrants. On this side of the Atlantic, the plan is to establish an intra-African bird migration project.
The MLSG organised a two-day satellite symposium just before the official EOU conference earlier this year in August. We had about 70 official attendees with another 20 or so dropping in informally, particularly on the day the EOU official started. Thirty nine attendees gave presentations – short summaries of these are given below. A visual impression can be found here, more info in text below.

Insectivorous birds consume an estimated 400-500 million tons of prey annually
The Science of Nature

For the first time, the predation impact of the insectivorous birds has been quantified on a global scale based on 103 (for the most part published) studies of prey consumption (kg per ha per season) of insectivorous birds in seven terrestrial biome types (i.e., tropical forests, temperate/boreal forests, tropical grasslands/savannas, temperate grasslands, croplands, deserts, and Arctic tundra).
Ten years tracking the migrations of small landbirds: Lessons learned in the golden age of bio-logging
The Auk Ornithological Advances
By Emily McKinnon and Oliver Love
Since miniature light-level geolocators were first deployed on small songbirds (2007), our understanding of migration for this group has grown exponentially. In this paper, 127 studies were reviewed that used geolocators to track small landbirds.
We are sorry to inform you that the planned EOU-MLSG satellite symposium "Landbird Migration in Different Worlds" at the IOC congress in Vancouver has been cancelled. The cancellation is due to an unexpected shift in timeslot as well as an overlap with a conflicting workshop on geolocator analyses. Instead, we encourage everyone interested, to sign up for the geolocator workshop organized by Eli Bridge, Simeon Lisovski, and Eldar Rakhimberdiev. Sign up here. The MLSG ExCo will still be present at the IOC to raise our profile.
