Bank swallows
Bank swallows

The bank swallow is a small migratory songbird that moves north to Canada each spring to breed and raise its young over the summer. Unlike most other songbirds, which build nests in trees, bank swallows dig nest burrows in substrates such as silty sand and other suitable materials. Suitable nesting habitats can typically be found in natural banks along bodies of water.

 

Mining activities often result in the creation of substrates similar to natural banks, enticing bank swallows to nest on active mine sites. This is dangerous for the birds, as those artificial banks are often unstable and can be impacted by mining activities such as blasting. The bank swallow is protected by the federal government as a species at risk, so it is imperative that our mining activities at IOC do not negatively impact their populations.

 

Since 2019, we’ve worked with local environmental contractors to survey and protect bank swallows on our property. We started by developing a Habitat Suitability Index (HSI) and map to identify areas on site that are suitable for bank swallow nesting. Using the map, we then conducted surveys to determine whether bank swallows were using those areas.

 

Each year, we continue to rank areas with the highest probability for nesting and conduct thorough surveys in spring and summer. These annual surveys have recently been expanded to include all areas with the potential for nesting, not just those with the highest suitability. If bank swallows are found, we take the necessary steps to ensure that they are properly accommodated. In 2023, two areas on the mine site were identified as active nesting colonies, and we took action immediately. The nesting areas were buffered, and our mining activities were adjusted to minimize any potential disturbance.

 

In addition to our annual efforts, we’ve implemented an ongoing awareness campaign to ensure that everyone working at the mine site knows how to recognise bank swallows. With our IOC community diligently looking out for these birds, we’re ready to take protective action whenever needed.

Pollinators

The smallest and busiest of creatures are often the most overlooked. Insects such as bumble bees, butterflies, wasps, and moths play a vital role in keeping an ecosystem in good health by pollinating flowering species so plants can reproduce.
