Birdlam: Oklahoma’s Big Day Birding Event!

When is Birdlam?

Our 3rd annual Birdlam will take place on April 22, 2023 (the fourth Saturday of April).

What is Birdlam?

Birdlam is Oklahoma’s big day birding event sponsored by the Payne County Audubon Society. The aim of Birdlam is to raise funds for Audubon chapters and other bird clubs across the state, increase general awareness of the avifauna diversity within Oklahoma, and … have fun!

Birdlam began as a nod to the “Bedlam” rivalry between Oklahoma State University and the University of Oklahoma. True to this spirit, the first Birdlam in 2021 was a friendly competition between the Payne County Audubon Society (OSU) and the Cleveland County Audubon Society (OU) for the largest tally within their respective counties. Beginning in 2022, the competition was opened to chapters and clubs across the state. Chapters/clubs may bird outside their club’s jurisdictions—just not beyond Oklahoma. The birdiest chapter/club will receive recognition and bragging rights. Participants are eligible for individual and group awards.

How Do I Get Involved?

Begin by registering online here. Registration is $30/person and you can pay your fee here. Every registered participant will receive a commemorative Birdlam t-shirt. Registration will be open through the day of the event. During the process, you will be asked to:

  • Choose a chapter or club to support (optional). A portion of your registration fee ($5) will go to that chapter or club.
  • Pick a t-shirt color. Options include orange, crimson, black, or heather gray in unisex sizes XS-XXXL.

Alternatively, you can register by emailing

Date: Saturday, April 22, 2023

Birding will commence at 12:00 a.m. and will continue through the following midnight. Birders may scout chosen territory in advance, but may only count species seen and/or heard during the specified 24-hour period.

What Are the Rules?

  • Please don’t count domestic, caged, unhatched, or deceased animals. Established populations of introduced species may be counted. Most current field guides should assist you in determining countable birds.
  • In the spirit of being as non-intrusive as possible, birds may not be called or enticed to respond by any means. Electronic devices are allowed so long as they do not disturb the birds.
  • Birds seen across the state line are permissible as long as the birder is in Oklahoma when the observation takes place.

Lists must be emailed or postmarked no later than April 24, 2023.  Please be prompt, and please be sure to identify the birder to whom the list belongs.
