How the total is calculated
- Feeder = the Amazon price of the listing we link (November 12, 2026). The Birdbuddy Home isn't on Amazon, so it uses Bird Buddy's store price.
- Subscription = the yearly price of the plan you choose × years. "Whatever unlocks automatic ID" picks the cheapest plan that turns on automatic species ID, which is $0 for feeders where ID is free (Birdfy, Humbirdy) or absent (Perky-Pet). For Kiwibit we also show the Lifetime AI option.
- Seed = pounds per month × price per pound × 12 × years (seed feeders). Hummingbird feeders use the nectar figure instead.
- Extras = a one-time amount for the pole, baffle and add-ons no feeder includes.
Subscription prices come from each maker's membership page where one exists (Bird Buddy), Birdfy's membership FAQ, and for Kiwibit the Amazon listing and The Gadgeteer's April 2026 review. Soliom and Camojojo don't publish AI terms on their listings and birdsnap doesn't publish its plan price, so those show $0 with a warning unless you enter your own yearly figure in the custom AI plan box; check the app before relying on species ID. Plans are optional on Birdfy, where species ID is free, so "cheapest" ignores them.
Feeders with unclear AI terms (Soliom, Camojojo) and those whose ID plan has no published price (birdsnap) show the feeder only. Add seed and extras in the true cost calculator.
A worked example
The defaults compare three years with automatic ID, 6 lb of seed a month at $1.68/lb and $51 of pole and baffle. The Birdbuddy Pro Solar costs $239 on Amazon plus 3 × $69.99 = $209.97 for Individual Premium: $448.97 before seed. Seed adds 6 × 1.68 × 36 = $362.88 and extras $51, for about $863. The Birdfy Metal 2 4K costs $219.99 with free ID, so the same seed and extras bring it to about $634, roughly $229 less over three years with a 4K camera. Over one year the gap is much smaller, because the subscription has only been paid once.
Notice how much of every total is seed: over three years it can cost more than the feeder. That's normal for any bird feeder, camera or not. Buying seed in 25 lb bags, using safflower or a baffle to stop squirrels emptying it, and choosing a hopper that doesn't spill all cut the real cost.
