21 May-21 June 2011: These are all the
points we got for Tucker, from deployment of his
transmitter until his untimely end when he flew
into a bus.
An interesting observation here is that nearly all the
points are connected directly back to the nest.
This means that almost all of his fishing
expeditions took less than an hour.
Scroll down for week-by-week comparisons of
Tucker's foraging patterns with that of his
neighbor North Fork Bob.

21 May-7 June 2011: One thing to remember as
we compare Bob (red 'F' balloons) and Tucker
(green 'T' balloons) is that Bob is not
raising young, while Tucker is feeding at least 2
nestlings.
Two differences here--Tucker spends quite a bit of time
hunting out in Long Island Sound. We don't know
how far off shore he's going, as each of these
points just captures where he was at the top of
the hour. He could have been heading further off
shore when his GPS recorded his location. We
also see that Bob tends to hunt farther from
home than Tucker. |

7-14 June 2011: This week Tucker was really
working the Sound, while Tucker mostly stayed
close to home, with the exception of a junket
all the way out to the easternmost tip of Long
Island on the 13th. |
|
14-21 June 2011: Bob really stayed close,
while Tucker continued fishing in the Sound.
The next three maps show the same time periods
focused in on the nest area. |
|
21 May-7 June 2011: Tucker likes fishing
down on Meeting House Creek where it feeds into
Flanders Bay. |
|
7-14 June 2011: Lots of fish out in the
Sound according to Tucker. Bob didn't get the
word, apparently. |
|
14-21 June 2011: Bob stays continues to stay close to home,
while Tucker, who's feeding a couple of young,
is still finding fish out in the Sound.
Shortly after these data came in Tucker was killed when
he collided with a bus. The only good news here
was that the transmitter wasn't damaged in the
collision, so we'll be able to deploy it next
spring on another bird.
The other bit of good news is that Tucker's mate was
able to rear at least 1 and probably both of her
young, doing the single parent thing with good
success. |
