Birdfy Nest Duo Review: My Own Private Nature Documentary

Although I’ve been a bird-watcher most of my life, nothing ready me for the expertise of witnessing—on my telephone—the whole means of birds being born in my very own yard.

I’ve maintained a daily “dumb” nest field for years, the birthplace of generations of black-capped chickadees. I’ve seen them going out and in, however I all the time puzzled what was taking place in there, particularly the 12 months I opened up the field within the fall and located 5 deceased fledglings on the backside. How may this have occurred? I puzzled.

Because of the Birdfy Nest Duo sensible nesting field and its built-in thermometer and hygrometer, I now not less than have an informed guess. (The poor issues probably overheated throughout an early season warmth wave.) With the ability to watch the whole nesting operation from all angles, beginning with excavation and egg-laying and ending in hatching and fledging, has been probably the most academic and entertaining bird-watching experiences I’ve ever had, and one thing I might suggest to anybody serious about birds, nature, or simply life science on the whole.

Eye Spy

Birdfy makes three sensible nest containers along with the Duo. The unique, the Birdfy Nest, has one digital camera—situated contained in the field—and might solely grasp from a watch hook screwed into the highest. There’s additionally a model made out of strong fir in distinction to the others’ light-weight bamboo. I’ve additionally examined Birdfy’s clever Polygon, however persistent connection points prevented me from utilizing it this season.

I’ve not examined the primary two single-camera variations, however I can not think about not having a second digital camera exterior the opening to see who’s unexpectedly poking their head in. (At one level in my testing, it was a confused flicker; one other, a curious starling—that is after I discovered chickadees can hiss). It is also vital to have the ability to pole-mount the field to maintain it away from predators.

The Nest Duo is substantial—16 inches tall and about 8 kilos—with one 1080p HD digital camera going through the nest entry gap on the outside and one other tucked discreetly contained in the nest field itself. There’s additionally an inside hygrometer (humidity) and thermometer (temperature) that present readings on the dwell view in Birdfy’s easy-to-use app. There are 4 easy-to-install, screw-on entry gap sizes for various species, from 0.9 inches for wrens as much as 2 inches for starlings or bluebirds, together with corresponding steel predator guards to forestall chewing. The complete aspect of the field opens with a latch for straightforward cleansing and entry.

Within the app, every display screen seize seems as a split-screen picture, which you’ll be able to faucet to view 20-second movies (with audio) of each the within and the surface of the field. The movies are instantly downloadable and shareable—no subscription is required.

The display screen captures work very like one among Birdfy’s sensible hen feeders, however with photos shunted to sections labeled “Prelude,” “Nesting,” “Brooding,” “Nestling,” “Fledgling,” and “Finish.” There appeared to be no rhyme or motive for what course of the app thought was taking place on the time (for instance, if a nestling was merely rotated, the app requested if it ought to label it as “Fledgling”), however this story format was simple sufficient to disregard onscreen.

Home Hunters

In March of this 12 months, firstly of nesting season on the West Coast, I put in the Duo with the 1-inch entry gap on a pole stand and mounted the included photo voltaic panel beneath the field with hose clamps. Black-capped chickadees have been constantly , popping in and looking out round, however one thing was stopping them from staking a declare. It took me some time to appreciate they have been trying askance on the holes on the steel tray “ground,” which is perforated for drainage. The concept is that this tray could be inserted into one among a collection of slots to extend or lower the nest cavity depth, relying in your native species’ desire.
