Report Details
A mild morning walk on mile 311 during an outgoing tide revealed 5 species of nudibranch, 3 species of anemone, and an impressive flock of 150 surfbirds that landed in the rocky outcroppings between Jockey Cap and Silver Point. Watching these birds feed and vocalize from such a close distance was special. Small numbers of black turnstone were also present. The loud piercing call of 2 black oystercatchers was heard as well. Harlequin ducks were bobbing in the surf and resting in the tidepools. A few dogs were off-leash. A few people were walking on rocks with barnacles. Large numbers of dried up velella velella (by-the-wind-sailor) were scattered above the high tide line. Large pieces of driftwood were washed up above the rocks high on the beach.
Conditions
Temperature: 53 F. Cloud Cover: Sunny. Wind Velocity: Calm/Light. Tide Level: 0.7 feet.
Human Activities
Number of people: 50. Number of dogs: 9. Walking or running: 16. Sitting: 30. Tidepooling: 4. Other Activities: I observed people riding bicycles and fat-tire bicycles, and two people were on motorized segways.. Some dogs were off-leash. A few people were walking on barnacle covered rocks in the tidepool area.
Notable Wildlife
Notable avifauna today included large flocks of shorebirds, foraging on the rocks, including 150 surfbirds, 15 black turnstones, 2 black oystercatchers, 5 Harlequin ducks, and my FOY in Clatsop County Orange-crowned warbler. Interesting tidepool finds included giant green anemone, moon glow anemone, and aggregating anemone (including one eating a granulated claw crab). I saw 5 species of nudibranchs, including Barnacle-eating Dorid (Onchidoris bilamellata), White-and-orange Tipped (Antiopella fusca), Horned nudibranch (Hermissenda crassicornis), Three-lined Aeolid (Coryphella trilineata) and the genus Aeolidia (shaggy mouse). Other good finds include mask limpet, gooseneck barnacles, ochre sea star, striped shore crab, fish eggs, and huge numbers of by-the-wind sailor washed up above the high tide line.
Driftline Content
Animal casings (e.g., crab, shrimp molt). Huge numbers of dried up velella velella (by-the-wind-sailor) washed up above the high tide line.
