Fall Migration Monitoring at the Lesser Slave Lake Bird Observatory has ended. We normally wrap-up September 30, but ran through October 3 this year since overnight temperatures were still relatively warm, potentially delaying movements of short-distance migrants. These three extra days were not enough, however, to find those missing migrants as counts fizzled into mostly… Read more »

Overhead songbird migration and captures have been slow at the Lesser Slave Lake Bird Observatory as the end of Fall Migration Monitoring nears, but that is not to say nothing interesting has happened. We caught a Pileated Woodpecker – only the thirteenth we have ever banded and the first since 2019! As Canada’s largest woodpecker,… Read more »

Every year, billions of birds from over 300 species migrate to Canada’s Boreal Forest to breed, and twice as many make the journey south to warmer wintering grounds.1 Some days at the Lesser Slave Lake Bird Observatory, we may see thousands of geese or songbirds flying overhead in the early morning hours, but this is… Read more »

Since the program’s inception in 2004, 2,248 of these pop can-sized owls have been banded. In 2016, our second target species, the slightly larger Boreal Owl, was added to the roster with fifteen… Read more »

Ask the field staff how the past week has been going at the station, and the response is SLOW! With fall arriving in the boreal forest, we are observing a significant slowdown in fall migration with captures of some warbler species slowing down to a trickle. We are also starting to observe flocks of migratory… Read more »

As August slips away many of our long-distance migratory birds have departed for Central and South America so our counts and captures have slowed considerably. Soon we will say our last farewells to the few remaining stragglers and welcome tundra-breeding migrants. We must also say goodbye to our seasonal staff. While it has been a… Read more »

August was passing uneventfully for the Lesser Slave Lake Bird Observatory until August 8 when a Black Bear approached within 5 m of field staff while they were yelling at it. Thankfully we always carry a canister of bear spray – even better, we have not yet needed to use one. We did not care… Read more »

Summer is slipping away fast at the Lesser Slave Lake Bird Observatory. By the time August is over, we will have seen the last of most of our long-distance migrants that arrived only a few months ago for a hurried breeding season in the boreal forest. Their long journeys seem to have been worth every… Read more »

After being delayed by high winds and rain late last week which brought a few small trees down over our nets and trails, the Lesser Slave Lake Bird Observatory finally completed our breeding-focused Monitoring Avian Productivity and Survivorship (MAPS) program on May 28, 2024. In general, MAPS went smoothly with a few delays caused by… Read more »
