Benjamin -- I had the same thought and then realized that if the sensors have decent clocks than you can calculate both. You get latitude from the duration of the day and then longitude from the placement of the day on the clock. This is a very creative method of light, low-power geolocation, I'm impressed.

One bird slammed on the brakes and took the long way around instead of flying over 500 miles of water...

If I'm a bird, and someone strapped a backpack on me that I wasn't born with--even a little one--I might have second thoughts about flying 500 miles over water.

Just wondering if the scientists are trying to correct in any way for possible alterations in the birds' behavior due to the study apparatus.

We note that there is a very large flock of
red winged blackbirds and grackles that did not migrate this very cold winter. They spend much of the day on our property in Putnam County eating. We wonder why this large flock decided to stay with us this winter.

The figures you mention on the drop in song bird populations seem very alarming - just another indicator that something's seriously wrong in the environment.

What can listeners do?

How can you get geographic location data from sunset/sunrise time? Since that varies both along latitude AND longitude, it seems you'd need some other data to correlate with it, and you need to know their exact location to get the speed.

IS THERE ANYTHING US regular PEOPLE CAN DO TO HELP THESE BIRDS????

Just curious if any of the birds tracked stopped off in Louisiana at Lake Pontchartrain. That is a notorious refuge for purple martins.

The map on your website shows that the flight path passes over a long stretch of the Gulf of Mexico. Do they fly non-stop over the water or are they capable of floating for a rest?

On telling location by the time of sunrise & sunset, does that work for both latitude *and* longitude? How?
