What these results show

These results show when people recorded a species, not when or where it occurs. Missing weeks and low counts do not mean absence or scarcity, and counts are not abundance. Contributed records reflect where, when and what people chose to observe.

Identification

How to identify it

Telling it apart

From what Ohio’s records show. Only what the records support is shown.

Often confused with

  • European Starling Sturnus vulgarisOften confused in Ohio: 15 identifications in Ohio named one where the other was meant
  • Song Sparrow Melospiza melodiaOften confused in Ohio: 10 identifications in Ohio named one where the other was meant
  • Brown-headed Cowbird Molothrus ater236 identifications worldwide named one where the other was meant
  • Common Grackle Quiscalus quiscula231 identifications worldwide named one where the other was meant
  • American Crow Corvus brachyrhynchos102 identifications worldwide named one where the other was meant

From iNaturalist’s similar-species counts, refreshed monthly: confusions in Ohio first, then worldwide. Only species with an Ohio result are listed.

When each is reported

  • All recordsUsually early March to early October, middle week early May · 6,337 records
  • Reported as maleUsually early March to early November, middle week early May · 662 records

Not every photo is marked with a sex or a sign, so these show when people reported each, not when it happens.

Finer identifications

Some Ohio records of this species were identified to a subspecies:

  • Agelaius phoeniceus phoeniceusEastern Red-winged Blackbirdsubspecies

Every one of these records counts toward the Red-winged Blackbird's season above.

Why some records go further than species

Many species vary from place to place. Groups of a species that look or sound a little different, and live in different areas, can be named as subspecies. Observers and experts only identify a record that far when it shows enough detail to tell them apart. Records without that detail count at the species level.
