The perky little chickadee with a black cap and deformed beak that I’d been trying to keep alive died a few days ago, the same day the 7.9 magnitude earthquake jolted me and fellow Alaskans out of bed.I knew it was only a matter of time.It mattered not that I’d been doing everything possible to accommodate the cute little guy’s needs by pulverizing nuts and seeds to make it easier for him to swoop up and swallow food with his crossed-sickle beak.Even without deformities, it’s tough for these birds, indigenous to Alaska, to survive the long and cold winters with daylight in short supply and 18-hour nights. They must eat constantly during daylight hours to regain the 10 percent body weight they burn each night staying warm.The poor little guy died as a result of chain migration, when a couple of opportunistic migratory birds called redpolls visited our feeders and came back with their extended family. Hundreds of them.
