Some migratory bird species are becoming more attracted to city life, yet these unnatural environments can be deadly. Swainson’s thrushes move from the north to central and northern South America every autumn.

Thousands of migrating birds make pit stops in cities around the world on their remarkable journeys that can cover thousands of kilometers. Why they chose to live in cities isn’t always evident Some seem to be attracted to the light. Others, such as the Swainson’s thrush in its berry-filled bush, look to be enjoying the feast. On the other hand, cities are not always welcoming to visitors.

Some migrating birds are killed by domestic cats, while others collide with structures. So, instead of being death traps, how can we make cities more like travel lodges for these animals? Swainson’s thrushes stop in Montreal for surprisingly long periods of time, where many of the birds molt — a process in which the birds shed and regenerate some of their feathers — according to Morales, a doctorate student at McGill University, and her colleagues. This assists them in preparing for the long road ahead of them. It’s the same as obtaining a new set of tires for your vehicle.
