How does air pollution affect pigeons?

In conclusion, our results suggest that pigeons homed faster when flying through highly polluted air.

What are pigeon adaptations?

Another unique adaptation of the common pigeon is that they possess the ability to “hover” for short periods of time. The pigeon readjusts her wings to counteract the gravitational force and balance them with the generated lift. This down stroke acts almost like a parachute, dramatically slowing the descent.

Ozone pollution directly harms birds by damaging their respiratory systems, and indirectly harms their food sources.

What is an indirect effect air pollution can have on birds?

Indirect impacts. Air pollution can also affect birds by triggering habitat changes, increasing parasites and reducing food sources (Morrison 1986; Graveland 1990; Eeva et al. 1994; Hörnfeldt and Nyholm 1996).
