Thread subject: A Few more interesting "tidbits" about osprey
Name Date Message
Celeste 05/10/05 07:30 pm A couple of weeks ago, Cecilia mentioned an out of print book written by Stephen Carpenteri...The Fish Hawk Osprey.......I was able to get a used copy(brand new condition by the way) through Amazon.com. (its really great Cec!)

The book is filled with colored photos that are spectacular.

A lot of the facts about osprey we have read in other books, but it is also a great book for referral and is great as a "refresher" course of osprey 101.

Just a few "tidbits" that I don't believe we have read on this board before.....

1. although feeding is important in pair bonding, some researchers have suggested that a solid, secure nest site is more crucial in whether or not a female ultimately stays with a particular male

2. We know that osprey pairs rarely separate, but when they do, it is because their attempts at nesting failed. What I had never read before is that some experts feel that the birds actually become more attached to the nest site than to each other, and that is what keeps osprey pairs together

3. Young ospreys tend to mate with birds their own age. Older birds though , (second decade), will select younger mates, because the majority of available single birds are usually 3-4 yrs olds mating for the first time. (we also know that a nest is more successful if there is a experienced male-and not so much if the female is experienced) Younger males are not as generous as older males in bringing fish to the female! Females will beg for food from any nearby male, including her mate,. Usually only the mate will bring her the meal, but sometimes a bachelor might bring her a fish.

4. Heavy spring rains can get an osprey so wet that they are unable to fly let alone fish

5. during the period when the female is most fertile, the male swoops low around the female whenever she leaves the nest, and often touches her lightly on the back or neck with closed talons if she strays too far or tarries too long.

6. When two yr old non- breeding ospreys do return to their natal nests, usually as late as June, they tend to "dally" around their former parents' nest sites, sometimes trying to take over a site, in preparation for their own breeding activities, which will take place the following year! For several weeks, these "teenage" ospreys can become a real nuisance to the nesting female, and sometimes can cause nest abandonment if they are persistent. Yet, sometimes these unattached males are available if something happens to a "paired" male. They sometimes "step-in" and help with the nest.

The United States has laws as we know that were passed in the early 70's protecting osprey, however, it wasn't until 1996 that the European Parliament voted to close the European Union hunting season on 74 species of migrating birds.

Shooting of raptors in parts of Central and South America continues to this day, and even in the US, ospreys are occasionally shot while in the act of taking fish from hatcheries or other waters where there is competition from harvestable or marketable fish populations...though this is rare.

There is so much to learn and admire about this bird!
Tiger 05/10/05 07:51 pm Thank you Celeste. A lot to consider there.

Jusdging by the supply of fish, our Dennis must be young indeed!
Cecilia 05/10/05 08:40 pm I'm so glad you're enjoying Carpenteri's book...it really is a great, basic osprey book with fantastic photos! I do think that he used Poole's book as a major reference (and he certainly gives Poole credit) but he kept the charts and graphs to a minimum and the photos are wonderful. Thanks for taking the time to share some of the interesting points...
I'm such a bad, slow typist that I just couldn't do it :-)
cathy 05/10/05 09:04 pm Thank you for this interesting information.
Kathy 05/10/05 09:09 pm Thank you Celeste, it's nice to still learn new things about Ospreys.
Tim P 05/10/05 09:32 pm As always, Thanx.
Keep the information coming.
Lori 05/10/05 10:20 pm Thankyou Celeste, I always enjoy learning when I don't have to do the "research"!
Marie 05/11/05 12:33 am Thank you Celeste...wonderful info. We can never learn it all in two or three seasons.
It takes dedicated folk like you and others to always be searching out new info for all of us.
BTW down at osprey junction here in Victoria, I found the female on eggs...how many I could not say but she didn't fly off the nest once during 90 mins I stood watching, She was so quiet but would often peer down at me . Her mate flew in only once after an hour with nothing. She murmered a few sounds of disappointment so he flew off toward the golf course ponds.I left after 30 mins because the baseball players were filing into the base ball diamonds and it was getting noisy and busy. I didn't like the wise cracks either about the camera equiment and the birds.Oh well everyone can't love ospreys!
karen 05/11/05 09:39 am Thanks as alway Celeste for being our researcher! I have a post it note on my computer with the name of the book but never got a chance to order it.
