🪶00:00 Eagles Rouse by raising feathers away from the body. Why they do it? To rearrange feathers, stay warm, intimidate an opponent, impress a mate, when they are excited, or just feel good.
🪶17:44 Allopreening - preening or grooming the skin or feathers of another bird. Usually directed at the top of the head, a part of the body not easily reached by the recipient. Notorious allopreeners: parrots and cockatiels.
☁️22:10 Pancake clouds aka. Lenticular clouds: You have no doubt seen them in the sky this winter, perhaps snapped a photo or two and used terms like "flying saucer" or "stack of pancakes" to describe them. So what exactly are those mysterious looking clouds and why do they form?
Known as Altocumulus Standing Lenticular (ACSL) or Altocumulus Standing Lenticularis clouds, they are associated with waves in the atmosphere that develop when relatively stable, fast moving air is forced up and over a topographic barrier that is oriented more or less perpendicular to the direction from which the upper-level wind is blowing. This deflection creates a gravity wave downwind of the topographic barrier not unlike a wave you might generate by throwing a pebble into a pond. When sufficient moisture is present above mountain-top level, ACSL clouds develop within the crest of these mountain waves where the air is rising. ACSL clouds are continually developing and dissipating in the vicinity of the wave's crest and immediately downwind of the crest, respectively. That is why they appear to remain stationary (hence the name) even though winds are swiftly (sometimes very swiftly) moving through the entire cloud. They are most often seen in the winter or spring when winds aloft are typically the strongest.

SoCal eagles are known to lay eggs as late as in late April, and so far Jackie and Shadow have been showing consistent nesting behavior: nesting materials, food gifts, pancaking and mating. We will patiently wait and see what they have in store for us.😊
Resident Bald Eagle male: Shadow (unbanded) since May 2018. Estimated hatch year: 2014
Resident Bald Eagle female: Jackie (unbanded) since September 2016. Estimated hatch year: 2012
