recording bird songs

The dawn chorus

Every year in the spring, park staff wake up early and record birdsongs at the same places in the park reserve’s forests. We send these recordings to bird experts who identify the birds.

Sidney island

Birds and deer

Our songbird data shows fewer birds on islands with an overpopulation of deer. The deer eat the understory bushes the birds need to nest, feed and hide. A fenced area on Sidney Island shows what happens when you keep the hungry deer out.

Happy bird day

Keeping track of trends in birds tells us what’s happening in the forest. In turn, we can fulfill our commitment to protect natural areas for present and future generations!
