Puget Sound and Islands > Seattle-Tacoma Area

9 of us from the Mountaineers naturalists met this morning in mild rain to see how many birds we could spot. 42 species included 5 greater yellowlegs (it's spring migration time! YESSSS!) good looks at a few very vocal marsh wrens, a pair of bald eagles, lingering waterfowl including some green winged teals, northern shovelers, wigeons, coots, gadwalls, a ring-necked duck, a great blue heron, and more. But not a single wood duck, and no beavers (on our wishlist).

We met at the Kiosk around 7:30 to learn that the University has changed decisions again on parking - now it's looking like come summer 2026, they'll allow free TWO HOUR parking, but beyond that, they'll collect money by license. Thanks to all those who protested; OUR COLLECTIVE VOICE MATTERS. 

We traveled clockwise to the waterfront, along the canal, and then had a 15-minute warm-up, restrooms, and refreshments break once the Horticulture Center opened at 9. Then on to Yesler Swamp which was surprisingly quiet with no wood ducks or swans. Nesting? or have they already left?

We saw evidence of recent blackberry removal throughout our journey; see photo below, piles lining the trail. Lake level is quite high, and mud is common near any interior ponds. Despite recent urban snowfall and abundant muddy areas, and a steady mist, our group left happy for having had our adventure and seen some great birds. The Fill never disappoints.
