There many delightful aspects to a feature rich bird feeder. To wit:
Notification via WiFi when the feeder needs refilling
Alerting bird-watching owners to arrivals
Detecting the attendance of rare or favorite species
Sensing—and potentially repelling—squirrel (or cat) predation
Profiling and tracking feedings by date hour and time of residency
Digital recording of songbird vocalizations
Tracking specific individuals by audio signature or visual appearance
Characterization of feeding preferences in a multi-dispenser system
Emitting invitational voicings to attract a wider variety of patrons
Prompting of owners to provide seasonal menu changes (e.g., suet)
Identifying early or late migrators and year-round residents
Assisting with bird counts or banding efforts
Band-detecting perches to aid migration and population assessment
Potentially registering the presence of wounded or ill fowl
That's more than a baker's dozen worth of features in somewhere around 20 minutes worth of brainstorming. Imagine the results if I was actually designing one.
