Silky Eggs?

Spontaneous generation just ain’t what it used to be. I’m willing to accept that maggots do not arise from spoiled meat, and suppose I can even believe that mollusks don’t magically become geese. But this time of year it’s really hard for me to imagine that the juvenile Phainopeplas that descend on our yard in such force could truly be the product of mere sexual reproduction.

Be honest: isn’t there something suspect in the fact that they arrive just when the bright orange fruits of the desert hackberry are ripening?
