Washington Mutual has hatched! The last time we had fluffy eyasses to watch downtown was in 2004, which seems eons ago, rather than only two years. While it is disappointing that two of the eggs did not hatch, we look forward to watching the two eyasses mature and to observing the adults taking care of them.
This is a new pair. Since neither is banded, we know very little about them, other than that they have been here since last summer. The female may be the same bird that attempted to nest on a ledge on the IBM Building last spring.
The peregrine population in the greater Seattle area continues to expand. We now have pairs at seven sites, and six of these pairs have laid eggs. All except the Washington Mutual Tower are on bridges. One site from last year – the Grain Terminal – is not active this year.
Four young at the I-5 Ship Canal hatched the last week in April. This is the fifth nesting season for the pair at this site; the previous two years have been successful. The male is from the Washington Mutual nest (hatch year 2001) and the female (hatch year 2000) from an Oregon site on the Columbia River.
The West Seattle pair fledged four young last year, for the first successful nesting season ever at this site. The pair did not use the nest box this year and laid eggs in a nearby expansion gap on the bridge. Observations of prey deliveries by the adults confirmed that eggs had hatched by May 1.
The pair of two-year-olds (hatch year 2004) at the Ballard Bridge had at least one young hatch by 5/2 or 5/3. The Ballard male is from the I-5 Ship Canal Bridge site, and his mate from a nest on a crane in Olympia.
After showing interest in a nest box provided for them, the pair of unbanded adults at our south Duwamish site chose instead to lay and incubate eggs on a small ledge that is out of view. This is a new site and a new pair.
The first youngster fledged from our one eastside site May 14th. This is a very early fledge date for the Seattle area. This is the 4th season at this site for the hatch year 2001 female from Portland. Her current mate is an unbanded adult male; probably the same bird who shared unsuccessful incubation duties last spring after the disappearance of her original mate (hatch year 2002, Washington Mutual).
An adult male from the 11th Street Bridge in Tacoma (hatch year 2003) is on territory on I-90 and has attracted a mate; the birds have not laid eggs.
The Grain Terminal is not active this year, and there have no recent sightings of birds at this site.
We had an anniversary to celebrate on May 2, 2006. On May 2, 1995, three peregrine eggs hatched on the WaMu tower. It was Bell’s first breeding season and the second for Stewart. Only one of the young, a male, survived past fledging. Because he stayed in Seattle his first two years of life, many of our volunteers were able to watch his adventures as a juvenile and young adult. When this little brown peregrine was only a few weeks post fledging, he challenged an adult female for her territory at the Grain Terminal, and the following spring he courted another adult female in Ballard. In his second winter, he courted a much older female that wintered at the I-5 Ship Canal Bridge for years. Our last confirmed sighting of him in Seattle was in 1997. Based on a partial reading of his VID (visual identification) band several years ago, we suspected that he was still alive. Last month, we were delighted at confirmation (via VID band reading) that the eleven year old male we called “Junior” is still alive and nesting in the Bremerton area.
