20 Sep-24 Oct 2010: Neale took the path more taken by adults down to
the Dominican Republic. He bounced around two weeks. He finally left for
points south on the 23rd. The map doesn't look good. It seems he's being
blown 90 degrees off his intended heading and he's going into the middle
of nowhere.
As expected, Neale did not make it. This is not one
where we can conjure up a scenario in which he will reappear next
spring. This is just the cost of trying to get across the Caribbean
during hurricane season. The mortality we see gives us a real feeling
for how important migration is. If it didn't provide a strong increase
in overall survivorship, it wouldn't be worth the risk.

The start of fall migration. |
|
The first week: As the breeding season progresses, I will post
weekly maps showing where Neale is fishing. In this first week, he went
over to the Pettaquamscutt River to fish. |
|
16-22 May 2010: The fish run over on the Pettaquamscutt seems to be
over. Neale is fishing more to the east, over in Newport. |
|
23-29 May 2010: Back to the Pettaquamscutt for some fishing this
week. |
|
7-27 May 2010: Here are three weeks' locations for all three
adult males we're following this spring. All three are travelling about
the same distances from their nests. Their foraging ranges are about 10
mi (16 km) across. |
|
30 May - 5 June 2010: The cluster of points on southern Conanicut
Island is at Mackerel Cove, which sounds like a good place for an
Osprey to hang out. |
|
6-13 June 2010: Neale made only 1 trip over to the Pettaquamscutt
River this week. Most of his fishing was on Conanicut Island or down on
Newport's southwest shore.
I'm including Sanford's locations. Sanford is a male
trapped on the Westport River. |
|
14-20 June 2010: Pretty much the same deal here. |
|
21-27 June 2010: Neale is expanding his hunting range a bit. |
|
28 June-4 July 2010: Neale continues to fish farther from home. On
the 29th, he went up to Prudence Island. The next day he made one big
loop over to the Sakonnet River, up to Prudence Island, and then back
home. |
|
5-18 July 2010: Neale is all over the place in this two-week period. |
|
19 July-1 Aug 2010: Neale is not going quite so far afield to catch
fish in the last 2 weeks of July.
|
|
2-15 Aug 2010: Neale is even more locally focused in the first 2
weeks of August. |
|
18 Aug-6 Sep 2010: Neale spent a lot of time down around Newport. He
should be heading south in the next couple of weeks. |
|
|
|
20 Sep 2010: Neale is heading south. He
left bright and early on the 20th before (7 AM), breezing through Long
Island. It looks like he took a bit of a breather (maybe 30 minutes)
around western Long Island or Northern New Jersey, as he only moved
about 13 miles(21 km) between 2 and 3 PM.
He covered 263 miles (423 km) on his first day of his
fourth trip south. We know this because he was banded on Block Island in
2006. |
|
20-23 Sep 2010: Neale passed over Cape May and Cape Henlopen and
traveled down the DelMarVa peninsula, crossing Chesapeake bay around
4PM.
After spending the morning probably fishing at the
Norfolk Naval Base, he only moved 56 miles (90 km) on the 22nd, passing
into North Carolina at 2PM.
He roosted on the Chowan River, where Gunny had been
the day before.
The blue track on the map was Thatch, our Delaware
youngster, who migrated down to West Palm Beach two weeks before Neale
moved down the coast. |
|
23-27 Sep 2010: Neale continues to follow the coast right in the
wingbeats of Thatch. In the next map we can see a couple how local
geography can funnel birds past certain locations. |
|
Fall 2010: These are the tracks of all eight of our birds that
migrated south using the conventional route (i.e. not out over the
Atlantic). If someone wants to count Ospreys migrating through the
Carolinas, the Lumber River looks to one of the spots to be. |
|
25-30 Sep 2010: Not much news here. Neale roosted close to Lake
Okeechobee, just west of Palm Beach on the 30th. He as 1293 miles
(2081 km) on the Osprey-ometer. Although he hasn't taken any rest days
so far, he's poking along at a rather slow pace--averaging 118 miles
(189 km)/day. 135 is more typical. |
|
30 Sep-6 Oct 2010: Neale left the Okeechobee area around 9:30 AM on
the 1st. At 3 PM he was over the Keys, heading south. Six hours later he
was 15 miles (24 km) from Cuba at 9 PM. He averaged 23 miles (37
km)/hour. Pretty standard speed.
Five days later he was just about done with Cuba,
roosting on the 6th just northeast of Guantanamo Bay. |
|
7-12 Oct 2010: Neale got to Haiti just after 4 PM on the 7th and
roosted 54 miles (81 km) into the country. He spent the morning along a
river in mountainous terrain (where he spent the night) and at 10 AM he
was moving east.
On the 8th he settled down for a few days at the
outskirts of the city of Dajabon just across the Haiti/Dominican
Republic border. He went south on the 12th, looking like he was going to
continue on to South America, but he returned the next day to the city.
(see next map) |
|
8-14 Oct 2010: This sort of makes us nervous. We have had too many
Ospreys shot in the D.R. to be happy with a bird hanging around this
close to a population center.
Neale spent most of this six day period working some
rivers southeast of Dajabon. |
|
18 Aug-6 Sep 2010: Neale once again seems to have started the next
leg of his migration and then aborted the trip. This doesn't look like a
bird that has found his wintering area, but rather one that's trying to
get on with migration, but not finding conditions to his liking. |
|
7-22 Oct 2010: Neale pretty clearly made two attempts to get off the
island, once southeast, and then another to the western end of
Hispaniola. The weather must have been bad both times. On the 22nd he
made another break for it, roosting in Haiti's extreme southeast corner.
On the 23 he took off for points south. Looks like he had a somewhat
easterly wind pushing him west as he headed for South America. |
|
22-24 Oct 2010: This looks really bad. 12 hours into his trip
south his GPS went off as programmed. 12 hours later when it came on
again, he was only 116 miles (187 km) east, going the wrong way. 10
hours later when we got the last signal for the day, he continued in a
totally inappropriate direction, heading into the middle of the
Caribbean, very far from any place to rest. He was only making 15.7
miles (25.3 km)/hour.
Before the advent of our new GPS transmitters, which
transmit altitude readings, I would have said he was on a boat. Now, I'm
not so sure, and I may have to re-examine the old records where I
thought birds had landed on boats (in some cases I'm sure they did). The
altitudes for Neale over these 10 hours were all over the place--552 m,
then 73 m, then 623 m, from hour to hour.
Two more days until his transmitter sends us data. I
can only hope he somehow finds Jamaica, but I'm not holding out much
hope on this one. |
