Latest Status on Sawgrass (3.30.17) -   Gabe Vargo

After being out of touch for almost 3 weeks, Sawgrass finally passed over a cell tower. Currently, she is in Honduras and still heading north.

There is a long void of positions. However, I'm not sure why. From southern Colombia to the first position in Nicaragua took 17 days over a distance of 2526 kilometers. That's really hoofing - or flapping it!

Hopefully, there will be better cell tower coverage for the rest of the trip and we will have a better idea of where she will take off point for her flight over the Gulf. Then I hope for strong southerly winds to bring her home quickly.

Sawgrass Latest Activity (2.10.17)

Sawgrass, was at the east boarder of Paraguay. She stayed there a few weeks before continuing east northeast into Brazil where the majority of our GPS-tracked Swallow-tailed Kites spent the winter season. She is now on a northward course following the same track of our other GPS-tracked birds that are ahead of her. She is 500 miles back from Palmetto, our second-to-farthest bird, and 1,400 miles from Bullfrog the Swallow-tailed Kite that is farthest north.  Interesting that Bullfrog and Sawgrass are our two birds that nested closest together in Florida’s Tampa Bay area, and they are the “book ends” of our 2017 migration story.    - Gina Kent

Sawgrass has traveled approximately 474 kilometers. See smaller red icons for the latest positions. From the last point in the lower cluster (Feb. 10) to the end point of the track on Feb. 13.    - Gabe Vargo

Sawgrass traveled 424 km from 2-10 to 2-13

Sawgrass in Argentina (1.11.17)

The latest positions for Sawgrass the Swallow-tailed Kite (STKI) as of Jan. 11, 2017. She has moved into a northern corner of Argentina. There's one wide view photo to show her general location, one close up for a better idea of the type of area she is in, and a final with a broad yellow line which shows the distance traveled on Jan. 8 - 43.26 km. She has then hung around this area west of some agricultural fields in N. Argentina.

Sawgrass Story

Sawgrass, the Swallow-tailed Kite from Sawgrass Lake Park in St. Pete.

She is wearing a backpack transmitter It sends out GPS locations when she comes close to a cell phone tower (essentially a text message).  Her backpack will store GPS locations and download them at the next cell tower with a strong signal.
