Hi birders,

Thank you all for continuing to build an incredible first year of the first
statewide California Bird Atlas. As of this writing, 160,228 Atlas
checklists have been submitted from 5,141 atlasers. The number of blocks
with data is approaching the 50% mark, with 8,202 blocks receiving some
coverage (49.63% of total blocks).

For more detailed updates, please see the following resources:

*ATLAS DISPATCH - JUNE 2026 REWIND*
For the most comprehensive updates on our progress, please read the latest
edition of *Atlas Dispatch *HERE

*TOWN HALL NEXT WEEK*
We will be hosting the 4th CBA Town Hall next week on Thursday, July 23 at
7:00 pm PT. This webinar will be hosted live on Zoom, and will be uploaded
to the CBA Youtube page <https://www.youtube.com/@CaliforniaBirdAtlas>
shortly thereafter. This Town Hall will feature Atlas news and updates and
feature a presentation on species that breed in the last half of the year.

*INTRODUCING: CBA CODE CHECK*
Code Check is a web app developed by CBA Science Director, Sam Safran, with
an interactive interface to look up the general acceptability of any
breeding code for each of California’s 345+ breeding species.

*NEW VERSION OF CBA BLOCKBOARD*
As requested by many, we’ve made Blockboard (the CBA Progress Dashboard)
easier to use on a mobile device. This should greatly increase its utility
as a reference when out in the field!
