Owl in 1970s: UK barn-owl nest boxes
[212] [desk-owl-0] In 1970s, the field log for Owl is headed “UK barn-owl nest boxes.” The figure kept beside that heading is 2. It is a count or a date from the work, not a rank of the species’ worth. A zoo birthday card does not replace the log. A large facial disc, soft pennaceous leading edges and a short tail for woodland turns. Many species add ear tufts that are display, not pinnae.
Nocturnal raptors whose facial discs, silent flight and asymmetric ears turn darkness into a hunting map. Why can some owls hunt in total darkness? Barn owls can strike by hearing alone. Asymmetric ear openings give elevation; the facial disc gives azimuth. Vision still matters in starlight.
The velvet and comb are strongest in forest nocturnal hunters. Fish owls and some burrowing species are noisier — water and day hunting change the trade. Are owls wise in the biological sense? Corvids and parrots outscore owls on many lab tasks. The “wise owl” is Athena’s bird, not a working-memory ranking.
Why did Harry Potter use a snowy owl? Hedwig is Bubo scandiacus, an Arctic lemming specialist. The films made a tundra bird the global pet-owl image — and briefly spiked illegal trade. Tyto alba can lay 2–12 eggs when vole cycles peak. Nest-box programmes in UK barns track that boom-bust directly.
