When Do Orioles Migrate North?

when do orioles migrate north

Orioles are beautiful, colorful birds and for most of us we get to see them during their summer migration. Although there are about 30 species of oriole, there are only 5 which we commonly see.

Some species are resident all year round, while others spend winter in the south and head north for their summer breeding season, returning south again during late summer and early autumn.

Here we look at the main 5 species of oriole visible in the US and find out where and when you can see them.

how to attract orioles

Baltimore Oriole

The Baltimore Oriole is sometimes confused with the Orchard oriole, as they do share some of the same territory and they are similar in color.

Baltimore Orioles are a vivid black and orange color. They can be seen during the summer as far north as the Canadian Prairies and Montana, and on south through to Mississippi, Alabama and Georgia. In the winter they prefer Mexico, Central and South and America. In some parts of the country they can be seen all year round.

Migration

  • April – May. Peak migration for these birds is from mid April to mid May. The early orioles reach Texas first then towards the end of May they reach the northern states.
  • June – July. They spend this time breeding and rearing their young.
  • August – September. The migration back south starts in August and hits its peak during these months.
  • October – March. During the winter months the Baltimore Oriole remains in the south.

Bullock’s Oriole

Bullocks Orioles are very similar in appearance to Baltimore Orioles, which is why they are so often confused for one another.

They have even been recorded as far north as British Columbia. During the winter they return to Mexico and parts of Central America.

Some Bullock’s Orioles don’t  migrate and can be found all year round on the Californian coast.
