April 19 [Day 55] (Valley View site) The temperature reached 14C at 1500 from a low of -1C and ground winds were generally W-SW light to 1100 then gusted 30 km/h to 1200 and gusted 40-60 km/h in the afternoon. Ridge winds were W moderate to strong becoming WNW after 1900, and cloud cover was 30-90% altocumulus, altostratus, cirrus and cumulus usually giving good observation conditions. The first raptor migrant was the day’s only Northern Goshawk at 1021 followed by a subadult Golden Eagle at 1029, but by 1420 only 2 further birds had been recorded. The pace then increased somewhat with 4 birds in the next hour and became positively vigorous between 1500 and 1600 when 15 of the day’s 34 birds passed. The pace then slackened again with the last bird, a juvenile Golden Eagle seen at 1931. Most of the movement was above the valley with relatively few birds following the ridge. A juvenile grey morph Gyrfalcon at 1420 was the 4th of the season, one of the 9 migratory Red-tailed Hawks was an adult dark morph “Harlan’s”, and the 18 Golden Eagles comprised 5 subadults and 13 juveniles. Neither of the resident Golden Eagles was seen today. 13.16 hours (610.4) BAEA 1 (393), NOHA 1 (8), SSHA 3 (21), NOGO 1 (80), RTHA 9 (127), GOEA 18 (2542), GYRF (1 (4) TOTAL 34 (3244)
