So I guess it makes sense.
12:21
Back in 2013, we were among a small group of scientists who started deploying these tags on... birds that were 10 grams or less.
12:32
And so these are most of your warblers.
12:34
At the time, we were basically testing out this technology on a small subset of birds in a pilot study.
12:41
And so we were studying golden wing warblers in the Appalachian portion of their breeding distribution in Tennessee.
12:48
And we put these tags out and geolocators are archival.
12:52
They're not like GPS.

So Gunnar, what do you want to call BS on?
6:09
Yeah.

They have all of these, these abilities to sense the environment that's around them and respond in ways that are going to be, um, or have in the past been adapted, right? They've evolved this capacity to, to react to inclement weather.
6:25
Instead of predicting, what I really think they're doing is they're responding, and they're doing so in ways that are really quite, uh, impressive to us humans who lack some of these same abilities, right? And so it looks really miraculous and, uh, uh, impressive for this tiny, you know, maybe like a nine-gram warbler to choose the right date and time to, for example, jump across the Gulf of Mexico or, um, change behavior in, in, um, light of some major severe storm.
