DIET: Mostly insects in summer, berries and seeds in winter. Forages in trees.
NESTING: Nest is built high in a conifer. From six to twelve light beige eggs are laid, incubated by  the female. Chicks fed by both parents.

CONSERVATION: When flying back from migration, the ruby-crowned kinglet, along with dozens of other species, is vulnerable to collisions with windows, particularly from high-rise buildings in cities. The city of Toronto is especially challenging because it is located by Lake Ontario and is in the middle of a well-traveled migration route.
NOTES: Very active bird, flicking tail frequently.
