A screenshot from the Migration Dashboard on BirdCast showing the number of birds in flight for the county as a curvy line. There are a couple of dips when rain came through and grounded birds.
We’ve had a couple brief showers move through tonight, followed by quickly clearing skies and it’s neat to see the birds respond to that via the BirdCast numbers.

Alright, here we go. BirdCast is back up and running. Birds pushing in front of those storm lines, moving NE.

Okay, so BirdCast seems to be broken tonight😭 but at least the radar composite map is still working. (Anyone from Cornell awake tonight? Does a switch need to be reset?😂)
These will be mostly short distance migrants headed north.

Oh, hey, is that a smidge of migration I see?!

Spring migration starts now! 🌺 🪶 BirdCast is a great way to see which bird species may stop in your yard on their way north. #Haikubox owners also get new bird alerts, so they know when new birds arrive.

This is a whole lotta birds. Turns off the lights for them. May they fly safe.

Look for things to get busy in the skies over Iowa, Minnesota and Wisconsin Friday night! Likely to be filled with birds! Another cold front dipping through early Friday. Behind it, a north wind picks up to aid birds in their migration southward. #IAWX #MNWX #Migration #Birdcast

That cool air sinking in behind the front means north wind. Birds are absolutely flocking south in droves tonight. Nearing in on A BILLION birds estimated to be in flight this evening. Just an absolutely massive amount of birds migrating tonight. #Birdcast #Migration
262 million #birds forecast to take to the skies tonight -
#BirdCast can help you follow their fall #migration.

I check BirdCast every night during spring and fall migration. The number of birds migrating is often staggering to imagine.

Hundreds of millions of birds are taking to skies each night, so many that you can spot them on weather radar. It’s data that researchers can use to estimate how many birds are in the skies and where they’re going.
💡Remember to keep your outside lights off this evening as the bird migration is still in full swing. 🪶

Another #warbler session in North Jersey. 11 species including 4 lifers. Our county and the county north of us had their highest number of migrating birds on #birdcast. Our top hotspot for warblers plus help from two experienced got me on several I would have missed #birding
Hey blue sky #birding #birdphotography community, is anyone here looking at or using #Birdcast? How are you using it? I work full time and need to pick my battles as to when I go out in am, and was hoping it could help... @birdsoftheworld.bsky.social
It's the early days of shorebird migration in the Meadowlands. Last night 87k birds migrated through Bergen County including yellow crowned night herons, semipalmated sandpipers and plovers and Forsters terns. I saw all 4 species on Sunday. Source: #birdcast. #birding #birdphotographer #NJbirding

BirdCast map showing approximately 18.2 million birds in flight at 10:50pm EDT on March 17, 2025. Migration is concentrated in southern and central Texas, flowing north-northeast.

Tomorrow night has the better conditions for a broader swath of migration, but tonight is showing a nice early influx at the border for the overland migrants, which is always pleasing to see. #birds #spring #migration #BirdCast
13 March 14:10 EST 13.6 million birds in flight. Love these maps from Birdcast! Just click below. #birds #Birdcast #birdmigration #nature 🌿🪶🦉

Tonight’s migration is trending more easterly at the start. While there’s not much precipitation wise to explain this, a look at the wind map shows more favorable tailwinds to the east and headwinds to the west.

it’s #birdcast season bb!

BirdCast migration map showing an estimated 19 million birds in flight at 9:40pm EST on March 3, 2025. The birds are headed north and most of the migration is concentrated in the southeast states with a little movement in Texas.
It’s #BirdCast season, baby!
These early stages of migration will be short distance migrants and “hardy” species that can push north early. Think sparrows, sapsuckers, Hermit Thrush, kinglets, Yellow-rumpeds, etc.
