People are encouraged to get involved in monitoring and data collection via tools like Merlin Bird ID and iNaturalist.

The theme this year is “Every Bird Counts – Your Observations Matter!” according to MigratoryBirdDay.org.

Seven ambassador species have been chosen to showcase this year’s migratory patterns: Cinnamon teal, Merlin, ruby-throated hummingbird, barn swallow, American oystercatcher, spoon-billed sandpiper and Abdim’s stork, according to the Migratory Bird Day information.

There are around 450 species of birds in North America that migrate two times each year. Four to five billion birds migrate south each fall, and nearly that number return north in the spring. Over a billion can be in the air at any given time during those migrations.

Some North Dakota birds such as ring-necked pheasants, sharp-tailed grouse, prairie chickens, wild turkeys and Hungarian partridge are residents and do not ever migrate.
