Bird list for Marymoor Park, Redmond, (King Co.) WA

BIRD LIST BY WEEK!
For a 5-page table showing species reported by week (instead of by month, as below),
in PDF format (requires Adobe Acrobat Reader, which you probably already have):
Click here.  Easy to print out on legal-sized paper. Updated 12/31/2020.

Frequency codes:

  • A --Seen on at least 90% of visits for the month - "always"
  • C -- Seen on at least 50% but less than 90% of visits - "common"
  • u -- Seen on at least 20% but less than 50% of visits - "uncommon" or less common
  • o -- Seen more than twice, but less than 20% of visits - "occasional"
  • r -- Seen only once or twice - "rare"

Note that the frequency data is constantly being refined through additional visits.  Note also that frequencies can change over time.  For example, American Bittern occurrence may be correlated with mowing near the slough, which only happens once a every few years.  Also, this bird list reflects the areas of my weekly walks, and not necessarily the park as a whole.

Understand also that these codes do not imply quantities.  One resident individual of one species will result in that species getting an "A" rating if the individual is always noted, whereas a roaming flock of 200 birds of another species may result in a "u" rating if they only visit about a quarter of the time.

PLEASE report any unusual sightings of birds at Marymoor Park to Michael Hobbs.  Use the table below as a guide to the "unusual" -- I'm interested in sightings in the "o" or "r" category, or anything not previously recorded for that month.

Bird list for Marymoor Park, 1990-01-01 through 2021-09-09
