</tbody></table>
Yesterday there were some private moments between the Osprey pair, so the question becomes when will we see eggs. It is a complicated answer.<br />
<br />
I found this information which may be helpful<br />
<br />
<div style="background: rgb(255, 255, 255); border: 0px; color: #333333; font-family: Georgia, "Bitstream Charter", serif; font-size: 16px; margin-bottom: 24px; padding: 0px; vertical-align: baseline;">
A male will land on a female’s back many times without this final contact being made. Studies have shown only 30-40% of attempts are successful. Early copulations stimulate the growth of eggs within the female’s ovary and strengthen the pair bond. The last 3 or 4 days before eggs are laid are the most critical for fertilisation.</div>
<div style="background: rgb(255, 255, 255); border: 0px; color: #333333; font-family: Georgia, "Bitstream Charter", serif; font-size: 16px; margin-bottom: 24px; padding: 0px; vertical-align: baseline;">
In a successful copulation the sperm travel to the female’s oviduct. This is where the various stages of egg development occur. First, the sperm fertilises an egg which has been produced during ovulation and already has a yolk. Then the principal coating of albumin is applied before the outer and inner shell membranes are added. These stages take about 5 hours. Next the calcareous shell forms. The background pigments are laid down. The egg stays within the uterus for about 20 hours and tiny glands excrete the streaks and patterns that result in the darker markings on the shell. Finally the egg is laid! The eggs weigh between 60 and 80g and are about the size of duck eggs. The background colour ranges from off white to pale brown, the mottling is red or dark brown. The first egg is usually the largest. Fascinating stuff!</div>

2017 Osprey Nesting Season</h2>
March 25, 2017<span style="font-weight: normal;"> the first osprey returned to the nest (coincidentally this was the same date as last year)</span><br />
<span style="font-weight: normal;"><br /></span>
Marcy 27, 2017 <span style="font-weight: normal;">the mate returned.</span><br />
<span style="font-weight: normal;"><br /></span>
<span style="font-weight: normal;">Osprey mate for life, but after breeding the osprey go their separate ways as they migrate, only to return to the family nest, so it seems unbelievable that they can come back from South America after being apart for months, within days of each other!</span><br />

So far we have clearly identified peanut bunker and perch. One of our osprey watchers has also seen koi (which are an ornamental sub species of carp bred and sold for their beauty, a favorite in ponds) Carp is a very hardy fish, tolerating more extreme temperatures than other fish. They are like the goats of the fish world, eating everything in its path, snails, plants, fish eggs and vegetation.<br />
<br />
If you spot a different species of fish email us and we will add it to the list, or get a screenshot of it and we will try to identify.<br />

When the female wants a fish she will start calling - <i>cheep, cheep, cheep -</i> ever more frantically if the male doesn't fast leave enough. Eventually the male will go off, catch a fish, and return, and as he comes into his mate's view she will again start calling - <i>cheep, cheep, cheep</i>. After he lands on the nest, she will continue to call until he gives up the fish and she eats.<br />

</tbody></table>
By bringing his mate fish the male is also demonstrating that he will be a good provider for the chicks when they hatch and need ever increasing amounts of fish as they grow. If the nest is successful three chicks can eat up to 60 pounds a day before they fledge.<br /><br />DRhttp://www.blogger.com/profile/18317351878942982194noreply@blogger.com0tag:blogger.com,1999:blog-3614083801174639896.post-34395564295049955282016-03-31T13:54:00.003-04:002016-03-31T15:02:16.463-04:00More about telling male and female Ospreys apart<table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody>

</tbody></table>
The difference between the female Osprey's breast marking and the male's relative lack of breast marking is clear in this image from the Osprey cam.<br />
<br />
If you are watching the nest cam and cannot see the breast of the Ospreys, these two have another distinguishing feature. The male has a distinctive partial eye ring that breaks up the dark eye stripe behind the eye. The female's eye ring is narrower and in some views almost invisible.<br />

In addition to making a better nest the activity reestablishes the bond between the pair.<br />
<br />
Before our volunteers installed the camera the old nest and platform were replaced with a new platform better able to support the camera. As with all of the other Osprey platforms we've replaced a small amount of grass and sticks were added as starter material.<br />
<br />

<br />
The Audubon Shop posted this about the Osprey this morning<br />
<br />
<span style="background-color: white; color: #141823; font-family: "helvetica" , "arial" , sans-serif; font-size: 14px; line-height: 19.32px;">Concerning Osprey: "Within populations, females average about 15–20% larger in body mass than males, and 5–10% longer in wing, tail, claw, and bill length. In addition,</span><span class="text_exposed_show" style="background-color: white; color: #141823; display: inline; font-family: "helvetica" , "arial" , sans-serif; font-size: 14px; line-height: 19.32px;"> females tend to have fuller, darker breast-bands and darker heads than males, although this varies among populations." (excerpt from an article by Alan F. Poole)</span><br />
<span class="text_exposed_show" style="background-color: white; color: #141823; display: inline; font-family: "helvetica" , "arial" , sans-serif; font-size: 14px; line-height: 19.32px;"><br /></span>
