Craniac Kid Rocks! |
Location: |
Main Office |
We
may be between migration and hatch, but that doesn't mean off-season
or inactivity for us at OM. Far from it. We're busy as beavers, and
that goes for many of our volunteers who help us out behind the
scenes as well.
Someone else who hasn't been idle is Ann Howden, daughter of OM
member Margaret Howden of New Glarus, WI. We've been told that Ann
is a 24/7 enthusiastic supporter of OM and Whooping cranes.
Ann chose to do her science fair project on Operation Migration and
the science behind the ultralight-led Whooping crane migration. Not
only did she receive an "Outstanding" rating from the judge, she was
specially commended for her in-depth knowledge of the subject.
How can we not be hopeful for the future of Whooping cranes and
other wildlife and their habitats when we hear about Craniac Kids
like Ann. Such interest and efforts are on their own, enough to
inspire anyone.
Congratulations to Ann from the OM Team! |

REFUGE SYSTEM ANNIVERSARY |
Location: |
Main Office |
Today, March 14th, is the 105th anniversary of the National Refuge
System.
We have two suggestions for a way to celebrate. Why not visit a
refuge near you, and perhaps inquire about opportunities to
volunteer there if you have some spare time.
Another great way is to buy a Duck Stamp to help with wetland
habitat conservation. All but 30 cents of the $15 cost of a Duck
Stamp is used for the acquisition or lease of new wetland/grassland
habitats. This initiative, which is administered through the
National Wildlife Refuge System, is one of the most effective and
successful conservation programs ever. Your support mean will help
them to continue to preserve America's disappearing wildlife
habitat.
Duck Stamps are available at most post offices and sporting good
stores. To find a place near you that offers the stamps, call the
Federal Duck Stamp Office at 888-534-0400. |

WAYS TO HELP |
Location: |
Main Office |
People often write to ask how they can help besides being a member or
donor. There are many ways, but here is a really simple one.
Wear your OM gear when you are 'out and about'. Having people see
that you support Operation Migration is of great value. In addition
to helping raise awareness for the project, it may present
opportunities for you to 'recruit' new Craniacs. So don your OM
t-shirt, sweatshirt or cap - getting spotted in your OM gear will
help Whooping cranes get the attention they deserve.
With our limited resources, one of the most difficult things to do
is to 'get the word out.' Whether by sporting our logo'd clothing or
having a Craniac sticker on your vehicle, you'll become immediately
identifiable as part of the effort to safeguard the Whooping crane,
and be providing more 'advertising and promotion' than we could ever
hope to achieve corporately. |

NEW VIDEOS |
Location: |
Main Office |
The 2007 migration turned out to be a marathon of epic proportions, taking every ounce of will, stamina, and patience that the entire OM team could muster. Attempting to encapsulate the 97 days spent on migration in any form for you to read at home is difficult. Yet throughout the 2007 (and early 2008) migration, we have attempted to do just that, illustrating our work through writing, photographs, and the occasional video.
Throughout the migration you would have shared in our growing frustrations as mother nature continued to plot against us. Day after day it seemed the weather would not cooperate, leaving us staring at the skies with a few choice words in mind. Yet, as the saying goes, “every cloud has a silver lining.” For us, that silver lining was the unadulterated joy we felt when flying alongside these magnificent birds.
While we’d like to share the pleasure of flying with the cranes with everyone, logistics and laws make this impossible. Nonetheless, I’d like to do my best to share this experience with you. In the
site map section of our website, we have created a link to our now complete 2007 Migration Video Journal. Here you can view 23 videos illustrating many aspects of our work, and perhaps, share in a little bit of the joy.
To visit the link directly,
click here or visit
www.operationmigration.org/videos. I’ve been asked by our technical people to remind you that the videos may take a while to load, but be assured that they all work.

EASTERN MIGRATORY POPULATION
UPDATE |
Location: |
Main Office |
|
This update for the
period ended March 8 was compiled from data supplied by WCEP's
Winter Monitoring & Tracking Team. The estimated maximum size of the
Eastern Migratory Population is remains at 76; 40 males and 36
females. * = females; DAR = Direct Autumn Release.
FLORIDA -

The juveniles roosted on or near the man-made oyster bar each
night with several exceptions. 15 Birds were led/herded, called, or
flushed into the pen on Feb. 24; 10 on Feb. 25; 10 on Feb. 26; and 1
(703) on Mar. 8. Around sunset on Feb. 29 a lone, northbound female
Sandhill crane landed at the pensite. She was met with aggression
but as the juveniles settled to roost for the night she joined them
on the oyster bar in the pen. The Sandhill left the pensite early
the following afternoon.
Maturation
Retaining their chick voices are: 710, 717, 722, 733, and
735.
Water
Levels/Salinity
Highest
recorded tide at the center of the oyster bar was 29 inches on the
evening of Feb 26. The Monitoring Team did not measure the higher
tides associated with the storm activity on the Mar. 7PM and Mar.
8AM. Salinity ranged
from 18 – 21 parts per thousand during the past two weeks.
Health Concerns
735 continues to have lack of extension of his right wing. She
was held longer than normal when handlers had difficulty fitting her
band at the time of the health checks on Feb. 4 and hasn’t been
flying. An examination by vets at Disney’s Animal Kingdom on March
3rd found muscle atrophy due to lack of use of the wing but no
fractures or other injuries that would prevent recovery of her
flight capabilities were detected. Recovery is not expected before
spring migration. No plan for this bird has been determined.

WOOD
BUFFALO-ARANSAS POPULATION UPDATE |
Location: |
Main Office |
|
Following his
most recent aerial survey, Aransas NWR’s Whooping crane coordinator,
Tom Stehn estimated that the flock size remained at a record 266
birds; 144 adults, 83 sub-adults and 39 juveniles.
"With the exception of one juvenile last sighted in November at
Muleshoe NWR, I think all the Whooping cranes are still at Aransas,"
said Stehn. "Other than for a few birds, it is usually not until the
last week in March that some of the cranes start the migration. The
majority of Whooping cranes remain at Aransas into April. They know
from experience that conditions are still frozen up north," he said.
"So far, so good," Tom said, commenting on the fact that there had
been no evidence of any mortalities over the winter.
Lobstick, a male crane banded in 1978, that had difficulty flying
earlier in the winter has apparently fully recovered. He is the
oldest known-aged bird in the population. One of its two chicks may
be ill however. On several occasions Tom observed the chick sitting
down, a behavior that often indicates illness. Healthy cranes rest
standing up.
"On this flight crane locations indicated a shift in habitat use,"
noted Tom. "Eleven cranes were on prescribed burns; 4 in uplands,
and 10 at or near fresh water sources. Bay salinities were 20PPT
when measured March 6, a level at which some cranes will move to
seek out fresh water to drink.
Tom said it was notable that 47 cranes (17.7% of the flock) were in
open bay habitat, presumably foraging on clams and other
invertebrates. "Blue crabs can occasionally be encountered in open
bay habitat however, and cranes have recently been observed still
finding large blue crabs to eat," he pointed out.
Visitors to the refuge observation towers have been provided with
good views of Whooping cranes recently as the Mustang Lake family
group has been spending time nearby.
During a coast-wide closure February 15 to 24, 38 people in 14 boats
picked up a total of 654 abandoned crab traps in Aransas and San
Antonio Bays, accounting for 50% of the total of the 1,300 coastal
traps retrieved. The traps, abandoned by commercial crabbers,
continue to catch fish and crabs and the occasional turtle if they
are not removed from the water. |

NUMBERS |

Since the reintroduction
project’s inception in 2001, a total of 126 juvenile Whooping cranes
have been released; 107 through the ultralight-led program and 19
via DAR. This total includes the only wild-hatched chick produced so
far, (W601) as well as two offspring of 2002 ultralight-led birds.
602 and 717 were collected as eggs when their parents (211/217* and
213/218* respectively) abandoned their nests. Both were hatched at
the Patuxent Wildlife Research Center, and included in the
ultralight-led program. The Class of 2007 also included 709, a chick
hatched from the wild-produced egg of a resident pair in the Florida
non-migratory population.
Mortalities in the reintroduced Eastern Migratory Population (EMP)
over the seven project years total 49. (See table below) Only 17 of
all mortalities occurred during the first six project years. More
than double that number occurred in 2007; 17 being storm-related,
and 15 due to various other causes.
The primary cause of death has been predation (18 birds). Other
causes include powerline collisions (3); gunshot (2); and, capture
myopathy (1). Cranes in the EMP currently number 76; a survival rate
of 60.3 percent. Excluding the mortalities caused by the unusual
storm event of 2007 as being outside the scope of normal attrition
gives an overall survival rate of 74.6%.)
In 2007 the first instances of alligator predation took place,
probably attributable to Florida’s severe drought conditions forcing
cranes to use the deeper water habitats that are home to those
reptiles.
