The reason is strikingly simple: because it really never does come here in Southern California. Call it what you will, but our winters are just summers in crappy, falling-apart Halloween costumes.
Lewis’ Woodpeckers (OC winterers) are essentially woodpecker-flycatchers. How can such a trumpy* thing exist? Ask the strange ways of evolution.
|Anything that has a huge, thick bill is automatically lovable. Like this, and this.|
The main difference that winter brings for me is that my suburban yard suddenly becomes completely devoid of anything flying and fruit-colored for a couple months. Unless you count adorable Lesser Goldfinches, which are sort of an aged, moldy banana shade.
Then, there's also the winter irruptions.
Apparently, SoCal's vacation vibe has infected this winter's irruptive avian visitors, which influxed faster than a load of twitchers to an ABA Code 7 and let birders across Southern Cal have looks that would make any Northerner birder go red.
