Helene,
Great summary, just one correction.
They do feed during the day, I see them doing it all the time in the
summer (both Wilson's and Leach's), however, they only come ashore and leave
their nesting sites after dark. Feeding forays can cover hundreds of miles.
Leach's petrels nesting on Kent Island in the Bay of Fundy travel as far as
George's Bank on a feeding trip before returning to their chicks, which can
take a couple of days or more. Nesting is staggered with some chicks only
now leaving the nests while others have been fledged since early September.
Leach's nest on many islands in the Maritimes but are often not seen because
of their nocturnal activities. I have a theory that some of the ghost
stories on islands where Leach's nest have their originals from the petrels'
nocturnal comings and goings.
We have a graduate student beginning a project next summer looking at
Leach's storm petrel's diet and contaminant levels in the food they
provision their chicks.

HI all,
Been planning to write about petrels in response to this question but
havent had time to get on. If you arent interested in the minutae of petrel
rehabilitation, stop reading now :)
I have had lots of storm petrels come in, or receieved calls about them,
typically after high winds. As most of you know they are pelagic seabirds
and are not normally seen on the mainland. They have a unique nocturnal
feeding behaviour where they literally skip along the surface of the ocean
skimming bits of zooplankton etc.
When they ar grounded on land, its like they literally have no idea what
to do. You can toss them in the air 100 times and they will just flutter to
the ground. However, take them to a beach or wharf or cliff..and toss them
and they will rapidly fly away ( unless they have some other problem). When
I get them in, i check them to be sure there are no injuries and they arent
thin ( they are usually fine). Then the next dusk that comes, I drive them
to Pictou and release them over open water and they fly off like a bat out
of hell. Nice releases. I try to release them where I can intervene if
necessary. I have had a couple who did not fly so I went in after them with
a dip net and boots...kinda hard to do off of a cliff :(
Because of their feeding behaviour they do NOT recognize anything you
might offer them as food, so if they are kept for an extended period they
will rapidly get thin. I once had one for a week ( landed after hurricane
Juan and I had no electricity for 5 of those days ) with a leg injury..so I
had to feed it with a stomach tube, no mean feat on such a tiny bird. It
was successfully released.
Some petrel trivia
- must be released at dusk or gulls WILL eat them. I once took my
boyfriend ( now my husband) on what I thought would be a cool release.
Tossed the bird in the air over Middle Cove in NL, it flew beautifully. As
we watched with binoculars, a great black backed gull swooped down and
swallowed him without breaking his flight pattern..ugh. I should have
listened to the locals!
- they smell like oil. Must be what they eat but they have a distinct
petroluem/fishy kind of smell
- they should be released ASAP, or they will get weak and thin
- again..they wont eat anything you offer them, no matter how good you
think it looks
- being a pelagic seabird, they and all birds who spend the majority of
their time on the water should be handled wearing gloves. Even oils from
your hands can mess with their delicate waterproofing. Also, their bedding
should be changed frequently, oils from their feces can also harm the
waterproofing on their feathers.
- do not try to swim them in your tub/sink/basin etc...especially if you
have hard water..again...hard on the feathers.
- consider yourself lucky if you see one, not many people do and they
are beautiful delicate little birds.
Sorry for the ramble, can you tell I like them?
If anyone finds one and needs advice, call me at 893-0253. The email I
have in my signature can be unreliable but I check birdvet@hotmail.com
several times per day.
Thanks

I don't have much experience with petrels, but I was speaking with
Helene van Doninck moments ago about this, and she informed me that petrels
will not fly unless they are tossed over water, and must be released at
night to avoid being predated by gulls.
However, grounded birds often have problems, emaciation/starvation
being one of them. If your friend is not sure the bird is healthy, he should
not release it.
Helene also tells me that petrels will not eat on their own in
captivity.
In addition, if a bird is weak from starvation, extremely careful
refeeding and special diets are necessary, because in the last stages of
starvation the energy it takes to digest food can actually drain the animal
past the point of no return and cause it to perish.
I suggest that the friend get in touch with Helene at the Cobequid
Wildlife Rehabilitation Centre for advice, and hopefully transportation can
be arranged to get it to her.
Helene says she will try and e-mail the list tonight with a more
comprehensive and expert reply than mine. :)
Helene can be reached by phone at at (902) 893-0253 or by e-mail at
