       American poet Celia Leighton Thaxter (1835 – 1894) was shaped by both environmental beauty and destruction she witnessed in her New England community. As a woman who spent much of her life on a small wind-swept island, she was educated by seasons and migrations that later informed her work. A brief education among Boston’s literary elite launched her creative career, where she focused on her local ecology. At that time, over-hunting and newly fashionable plumed hats and accessories had created a serious possibility of avian decimation. By creating awareness of humans’ culpability for birds’ endangerment, Thaxter’s work evoked public sympathy and contributed to social and political change.       This essay applies ecofeminist and cultural analyses to Thaxter’s work written as part of the 19th century bird defense movement, by examining the emotional rhetoric employed and activism implied in her poems and prose about birds, specifically: “The Kittiwakes,” “The Wounded Curlew,” and “The Great Blue Heron: A Warning.”  Little attention has been paid to Thaxter’s didactic poems which use birds as subjects to instruct children and adults about the fragility of birdlife and to warn of humans’ destructive behaviors. These works illustrate Thaxter’s ecological sensibility and her use of emotion and reason to communicate an ecological message. Her poetry and prose about birdlife fortified the budding Audubon Society and contributed to the birth of the environmental movement. We can learn from such poetic activism, from attention to nature turned commodity, and the dangers of depleting finite resources. In our global environmental crisis, we recognize the interwoven relationships between birds and humans. Perhaps poems can help stymie our current ecological trajectory.

An array of predators that consume juvenile salmon (Oncorhynchus spp. Suckley‎, 1861)‎ may account for the poor returns of adult salmon to the Salish Sea. However, the Pacific great blue heron (Ardea herodias fannini Chapman, 1901) is rarely listed among the known salmon predators, despite being regularly seen near salmon streams. Investigating heron predation by scanning nesting sites within 35 km of three British Columbia rivers for fecal remains containing Passive Integrated Transponder (PIT) tags implanted in >100,000 juvenile salmon from 2008-2018 yielded 1,205 tags, representing a minimum annual predation rate of 0.3–1.3% of all juvenile salmon. Most of this predation (99%) was caused by ~420 adult herons from three heronries. Correcting for tags defecated outside of the heronry raised the predation rates to 0.7–3.2%—and was as high as 6% during a year of low river flow. Predation occurs during chick-rearing in late spring, and accounts for 4.1-8.4% of the heron chick diet. Smaller salmon smolts were significantly more susceptible to heron predation than larger conspecifics. The proximity of heronries relative to salmon-bearing rivers is likely a good predictor of heron predation on local salmon runs, and can be monitored to assess coast-wide effects of great blue herons on salmon recovery.
