Barred owl fledglings thriving across the lowland woods

have fledged their young here, with at least one brood confirmed flying on July 4th. Over the past three months, 24 sightings across the wooded edges of Bellingham and Whatcom County trace the species' spread — not simple breeding in place, but active colonization of new territory.

What makes this particularly striking is the ecological cost. Barred owls arrived in Washington only in the 1970s, having expanded northwestward from eastern forests over decades. They are now so thoroughly displacing native spotted owls that federal biologists have resorted to removing barred owls in an effort to preserve their rarer competitors. The success of these fledglings signals that the barred owl's takeover is continuing — even as conservation biology struggles against it.

Orca sightings have been steady through spring — 57 records over six months,…

June 25, 2026

sightings have been steady through spring — 57 records over six months, with both ecotypes present as of mid-June. The mix matters: Resident and Transient orca have very different diets and seasonal patterns, and seeing them together suggests variable prey availability across the region.Humpback whales are also moving through, 23 sightings in the same window, and the pattern tells a food-web story. Humpbacks have rebounded partly because Pacific herring populations are stable enough to support their spring feeding. Southern Resident orca, by contrast, feed almost exclusively on Chinook salmon — and those populations have not kept pace with recovery. One humpback sighting can mask the struggles underneath.

Three Bellingham permits go dark on reporting at once

August 16, 2026

Three of the largest permitted dischargers in the Fraser Lowland are currently listed in significant non-compliance with federal regulators, and in all three cases the problem is not a documented pollutant release but a failure to report at all. The Bellingham wastewater treatment plant, which discharges near Bellingham Bay, missed its required monitoring report entirely, the first time this plant has shown up flagged at this location. At the same time, the Bellingham City stormwater permit and the Port of Bellingham permit are both listed more than 30 days late on their compliance-schedule progress.The distinction matters. This is not three facilities caught discharging over their limits; it is three facilities whose self-reported data has gone missing at the same time, which means there is currently no way for anyone outside those facilities to check what is actually entering the bay. The federal impairment list covering roughly 50 nearby water bodies, including the Bellingham Bay segments near the plant, shows none officially impaired, but most carry a label of insufficient data to determine impairment, a designation left over from the 2018 assessment cycle. That is not the same as clean water. It is another version of the same gap: an absence of monitoring record rather than a finding either way.Late summer is exactly when a reporting blackout like this is worth watching closely. Warm, still water this time of year already carries elevated risk for dissolved oxygen stress and algal blooms in nutrient-loaded systems, and Bellingham Bay sits downstream of a treatment plant now sitting quiet on its reporting duty. None of this proves a discharge problem. It does mean that the paperwork which would let anyone confirm one way or the other is simply not there, across multiple permits, at the same time.

Indian plum fruits feed jays in early summer

June 26, 2026

The understory along the trails at Sehome Hill Arboretum is dense and green right now, the bigleaf maples and vine maples filling in overhead so fully that the light comes through in patches. Down in the shrub layer, Indian plum has already made its move. While most shrubs are still in flower or just beginning to set fruit, Indian plum is ahead of all of them. The small, olive-colored fruits hang in loose clusters from branches that leafed out back in late winter, the earliest woody plant in the understory to do so. By early summer, those fruits are ripening to blue-black, and the Steller's jays know it.Indian plum is a native shrub of the Pacific Coast understory, common in second-growth forests, woodland edges, and the kind of mixed shrubby habitat that runs through the arboretum here. It flowers in late winter, sometimes while snow is still possible, and fruits months before most other shrubs in the same community. Oceanspray, which is blooming right now with its creamy white flower clusters, won't fruit until late summer. Snowberry holds its white berries into fall. Indian plum doesn't wait. That early fruiting is the point: it makes itself available at a moment when almost nothing else does, and the jays are one of the animals that takes full advantage of it.Steller's jays are corvids, closely related to crows and ravens, and they carry the intelligence of that family into everything they do with food. They don't just eat what's in front of them. They cache. A jay will take a fruit, sometimes swallow it whole, sometimes carry it to a branch and work it apart with its bill, and sometimes fly off with it to store it somewhere else entirely. In nesting season, which is happening right now, the behavior shifts slightly. Adults are feeding young, which means they need high-energy food reliably and often. Indian plum's fruits are small but calorie-dense, and the timing lines up with the period when jay pairs are making the most trips back to the nest. If you hear that sharp, scolding call somewhere in the canopy above you, and then a brief silence, and then the rustle of something moving through leaves, there's a reasonable chance a jay just landed in an Indian plum and is working through the cluster.The relationship runs in both directions. Steller's jays are effective seed dispersers. A jay that swallows an Indian plum fruit whole and flies two hundred meters before digesting it has moved that seed somewhere the parent plant never could. The seeds that pass through a bird's gut often germinate more readily than those that fall directly beneath the parent shrub, partly because the pulp has been removed and partly because they land somewhere with less competition from the parent plant's own root system. Indian plum's early fruiting isn't just about being first to attract birds; it concentrates dispersal at a moment when jays are active, hungry, and moving constantly through the forest. The plant is not passive in this. It produces fruits with thin, easily digested flesh around a hard pit, a structure that rewards quick consumption and increases the chance the seed survives the trip.

Barred owls fledging young across the San Juan Islands

July 13, 2026

have moved into the San Juan Islands and are now raising young here — fledglings confirmed as recently as early July, with fifteen sightings recorded across Orcas, Lopez, San Juan, Guemes, and Anacortes over the past six months. These are eastern birds, expanding westward across the continent for decades, and their arrival marks a turning point in the archipelago's woodland ecology.Barred owls aggressively claim nest cavities from northern spotted owls and readily interbreed with them, creating hybrid young that further dilute the spotted owl's genetic integrity. Island by island, year by year, the displacement is measurable and still advancing. Where barred owls establish, spotted owls retreat — not in a season, but in a steady, documented erosion of territory that echoes across the region.
