After I first turned a critical birder 15 years in the past, I wanted there was a method to simply entry historic birding information. What might you see at this park in October? That sort of info simply wasn’t simply accessible. Then got here eBird.
As soon as I began studying determine birds by ear, I longed for a software that would assist me determine that bizarre chicken name I used to be listening to. Then there was Merlin SoundID.
And as I turned a die-hard chicken nerd, I’d plan my spring and fall journey round migration. I knew April-Might and September-October had been the perfect months, however there was no method to know if any sooner or later or week was going to be significantly good birding. That’s… till BirdCast got here alongside.
BirdCast gives real-time predictions of chicken migrations: when birds are migrating, the place they’re going, and the way far they’re flying. The sheer scale of the info is unimaginable, and it’ll change the best way you chicken throughout migration.
From Enemy Plane to Birds
BirdCast makes use of the identical climate radar information that you simply’d see in your nightly climate broadcast to foretell the numbers and flight instructions of migrating birds.
Radar expertise was developed to detect enemy plane throughout World Battle II, after which shortly expanded to its present utility in climate forecasting. But early radar engineers had been puzzled by unusual dots on their screens that didn’t correspond to recognized plane or storm techniques. Finally, two ornithologists labored out that radar might additionally detect lots of migrating birds. That was the start of a brand new scientific area: radar ornithology.
As computing energy and information storage grew, researchers developed pc algorithms to separate chicken detections from meteorological phenomena, or plane, or bugs, and even bats. By 2018, the expertise was superior sufficient that BirdCast might deliver real-time migration forecasts on to birders in the USA. The freely accessible software is a partnership between the Cornell Lab of Ornithology, Colorado State College, and UMass Amherst.

Prepared, Set, BirdCast
The BirdCast website has a wide range of instruments you need to use to up your birding sport:
- Forecast maps that predict how a lot, the place, and when chicken migration will happen.
- Reside migration maps that present how a lot, the place, and when migration is going on in real-time.
- Migration dashboard that gives radar-based measurements of nocturnal chicken migration at county and state ranges within the contiguous US.
- Migration alerts that inform you when intense chicken migration will happen close to you.
We suggest beginning with the three-day forecast maps, that are the primary maps you see on the BirdCast homepage. These maps present the predicted nocturnal migration 3 hours after native sundown. They cowl a three-day interval (one map per day) and are up to date each 6 hours. The lighter the colour, the extra intense migration will likely be. The maps additionally incorporate climate techniques, which might have an effect on migration at an area scale.
Identical to climate forecasts, these maps mix a number of variables: wind velocity, path, barometric stress, temperature, and 25 years of migration information. They need to provide you with an concept of what migration will appear to be over the approaching days.
Subsequent, scroll all the way down to the second map, which reveals real-time info on the depth and path of migration, as detected by climate radar between native sundown and native dawn. These maps have an analogous shade scheme, noting migrating depth, together with arrows to point out the prevailing flight instructions. By hitting the “Play” button within the decrease left, you may watch the reside information because the evening progresses.
However wait, how does figuring out the place birds are at evening translate into higher birding?
All of these birds flying overhead should land every morning to relaxation and refuel. Understanding the relative depth of migration in your space may help you decide the perfect days to go out together with your binoculars for some migration magic.
Earlier than you permit within the morning, verify the Migration Dashboard for county-level information. That is the software that may inform you what to anticipate at your favourite birding hotspot.
The quantity of element right here is considerably mind-boggling. BirdCast can inform you the variety of birds in flight (in the course of the earlier evening), their flight path and velocity, in addition to their altitude. And by integrating eBird information into their predictions, BirdCast offers customers a listing of the birds which might be flying overhead, and that you simply’re almost definitely to see in the course of the subsequent day’s birding.
For instance, birders in Chicago this week ought to hold their eyes peeled for: American redstart; warbling vireo; frequent nighthawk; rose-breasted grosbeak; and blackpoll, black-throated-green, palm, and bay-breasted warblers.
In case you don’t have time to verify BirdCast daily, you may join the migration alerts that notify you when intense migration is going on in your space.
Forecasting runs throughout each spring and fall migration in North America.
And whereas we’re speaking chicken tech… In case you haven’t already checked out Merlin Sound ID, drop what you’re doing and obtain the app proper now.
As CGS author Cara Cannon Byington notes, Merlin Sound ID is like Shazam, however for birds. While you hear an unfamiliar chicken sound, simply open the app and begin recording. Merlin magic does the remainder, utilizing spectrograms Cornell’s huge repository of sound information to determine no matter you’re listening to.
It’s not an understatement to say that my jaw dropped the primary time I used it. Sound ID at present covers North America and Europe, with plans for additional expansions. I’m counting down the times till they add Australia.
Now get out and go birding.
