A banded juvenile male from northeast Seattle, perched on a dead-top tree near the nest site, a preferred perch site for Merlins.
Juvenile Merlins perched near their nest site. Recently fledged siblings often hang out together for 3-4 weeks and continue to be fed by their parents before they disperse.

The first documented Merlin nest in Seattle was found by Kim McCormick in 2008, after several years of searching. The nest, in a northeast Seattle neighborhood, successfully fledged five young. Kim noticed that the adult female had a federal band on one leg; after a patient effort, she learned that the Merlin had been banded by local raptor researcher Jack Bettesworth. Kim continued to document Merlin activity for the next several years, and through
Merlin Project For the Mobile Project Manager With the flagship of our products you plan and organize projects of any size - in the office, on the road and remotely from home. Lone fighters and teams love the intuitive operation and effortless data synchronization between all their devices. Project Merlin In a future world forecasts suggest distributed energy resources (DER) will be fundamental in reducing costs associated with increasing energy demand from electric vehicles (EVs) and variable power flows from renewable generation. Merlin Project is a project management (PM) solution natively written for macOS and iOS. It caters to businesses of all sizes across various industries.
Ben Vang-Johnson and Kim McCormick gave a Zoom talk for Pilchuck Audubon in November 2020. They presented highlights of the Seattle Merlin Project, including nest site characteristics, behavioral observations, and urban habitat adaptations.

Report a sighting
Contact URC to report a sighting of a banded Merlin, possible breeding activity, or general observations in the Puget Sound area.
Merlins are color-banded (red in previous years, now blue) on one leg (females: left, males: right) and a silver federal band on the other leg. Each color band has a two-character ID code.
If you find a Merlin through a spotting scope or powerful camera, watch for a colored band if it stretches or moves.
Project Goals
In 2013 Kim and Ben started the Seattle Merlin Project. The project uses nest searching, nest monitoring, banding, year-round observation, nest tree measurements, and remote sensing landscape characterization to:
- Determine fidelity of breeding and wintering sites and of breeding pairs
- Document annual spatial movements of individuals breeding or wintering
- Determine annual nesting success and productivity of breeding pairs
- Estimate nesting density
- Investigate natal dispersal of juveniles
- Describe nest site characteristics, plumage characteristics, and other natural history
Results
This urban-nesting Merlin population is expanding.
- In 2018, 18 pairs were found in the Seattle metropolitan area and 14 fledged young. Within the city, 7 nesting pairs were found and 4 fledged young.
- In 2013-2018, 79 active nest territories were documented and monitored in Seattle and the surrounding region. 62 of these nests fledged young—a success rate of 78.5%!
- As of 2018, the project had banded 77 Merlins, recorded over 200 banded Merlin sightings, and were able to read the IDs on over 100 of these bands.
The Seattle Merlin Project documents more and more nests each year as we get better at finding Merlins and learn more about the local territories. We are probably also documenting the expansion of this young urban and suburban Merlin population.

Merlin Project Management Review
Adult male Taiga Merlin. Taigas are found in Seattle during migration and winter seasons but are not known to breed here. Compared to the Black Merlin below, Taigas have broader white tail bands (not shown), cleaner throat, lighter and thinner breast streaking, and lighter head, cheeks, and supercilium (eyestripe).

Adult male Black Merlin banded in Seattle. Black Merlins breed locally. They have much thinner and broken white tail bands (not shown), more throat streaking, darker and heavier breast streaking, darker head and cheeks, and a smaller supercilium.
