616 Sept-15 Oct 2011: Henrietta was our
first bird to start migration this year. She
left Martha's Vineyard around 6 AM on the 16th.
15 hours later she was 464 miles off shore,
averaging over 30 mph. She then probably lost
her tailwind, as her speed dropped over the rest
of the crossing. She made landfall about 43
hours after taking off, having covered about
1097 miles.
She cruised right through the Bahamas, Cuba, and
Hispaniola, and was safe and sound in Colombia
on the 26th, just 11 days after leaving home. |
|
16-22 July 2011: Henrietta has been making a
few short flights around her front yard. |
|
27 July-5 Aug 2011: Henrietta is beginning
to explore her world. James Pond is what we like
to call the baby pool. Lots of our young birds
wind up over there as they're beginning to learn
to hunt.
And, she made her first trip "off-island." For native
humans, this is usually a trip to Costco or
Trader Joe's. For our Ospreys, it's a fishing
expedition to Naushon Island in the Elizabeth
Island chain, or a junket to Cape Cod (see the
next map). |
|
6-14 Aug 2011: Henrietta discovered Long
Pond north of Falmouth. We've had other young
Ospreys from Henrietta's nest find this same
pone. |
|
15-21 Aug 2011: One road-trip to the Cape. |
|
21-28 Aug 2011: Henrietta made one trip to
the Cape to go back to Long Pond. |
|
29 Aug-7 Sept 2011: Henrietta hunkered down
during the nasty weather caused by the remnants
of hurricanes Irene and Lee. |
|
6 Aug-7 Sept 2011: Henrietta's locations for
a month post-fledging. The Cranberry Bog is just
above Duarte's Pond. It probably has a local
name, but that's what it's called on the Topo
maps. |
|
8-15 Sept 2011:
Henrietta stayed close to home, bouncing back
and forth between Lake Tashmoo and her favorite
fishing spot a few miles away. She took off
bright and early on the 16th, leaving the south
shore of the Vineyard behind around 6 AM. |
|
16-18 Sept 2011: Henrietta took care of this
corner of the Atlantic in about 43 hours,
averaging a healthy 26 mph over the non-stop
trip. |
|
18-20 Sept 2011: Henrietta arrived at Great
Abaco Island around 1 AM on the 18th. She didn't
linger long to rest. She spent the night of the
18th on tiny Rose Island just east of Nassau.
The next day she hopped over to South Andros Island,
where our adult male, Sanford, from the Westport
River spent last winter. She left Andros around
3:30 PM on the 20th and then settled down on
Cuba's north shore for the evening. |
|
19 Sept 2011: Henrietta probably spent the
day fishing on South Andros. |
|
20-23 Sept 2011: Henrietta took just a
couple of days to cover the eastern part of
Cuba. She may have been counted by our colleague
Freddy Santana, who maintains a hawk count at
Gran Piedra, just west of Guantanamo Bay.
She left Cuba just after 1 PM on the 23rd, and settled
down to roost in northern Haiti that night.
At this point she had covered 1,892 miles in 8 days,
averaging 234 miles/day. |
|
23-26 Sept 2011: No moss growing on this
stone! She apparently had clear sailing across
the Caribbean and made it in about the shortest
distance possible.
She left Cabo Beato in the D.R. around 9 AM. 9 hours
later she was 187 miles (300 km) out over the
Caribbean, almost exactly half way across the
Caribbean. Assuming she kept up her average
speed of about 20 mph, she probably made
landfall on Colombia's Guajira Peninsula around
3 AM on the 26th.
After catching a few winks and perhaps a fish, she
explored the Peninsula roosting that night on
its easternmost shore. |
|
26 Sept-15 Oct 2011: Judging from her first
location in Colombia, she may have come in a bit
more from the west than the track connecting her
last point on the 25th to the first on the 26th.
This set of data had the first obviously wrong GPS
location I've seen. The indicated fix can't be
right. She couldn't have gotten up there an back
between the two surrounding GPS locations. |
|
20-23 Sept 2011: Henrietta spent a few days
exploring the arid Guajira Peninsula. Because
it's the northernmost point of land in South
America, lots of Ospreys arrive here in the fall
and many leave here in the spring. |
|
29 Sept-15 Oct 2011: Henrietta found the
mangrove wetlands where Buck spent a lot of time
over his first year and a half down in S.A.
On the 15th she took off and wandered around a bit
before heading on on what looked to be the
beginning of an exploratory mission.
The signals on the 15th were the last we got from her.
This one's a total mystery. She wasn't near any
apparent human activity, so we really can't
speculate as to what happened. |
