Blog #357Graduating Class of 2021

The graduating class of 2021 Cayuga Lake Ospreys have winged their way to the Caribbean and South America and are looking for places to live on the coast or along a tropical river.  Before migration, the young Ospreys were in the constant company of their siblings eating,  sleeping, and playing together as a family. But for the last six weeks, each juvenile has been on a solitary quest southward to a place it has never been, unaided by including parents,  siblings, friends, or a map humans can detect.  

Migration is one of nature’s great mysteries. While theories abound, no one knows how  juvenile Ospreys know where to go. Instinct must play a major role, acting like a sixth  sense compelling an inexperienced bird to move southward, but other inexplicable  forces are at play. 

Tracking Ospreys wearing miniature satellite transmitters, researchers have revealed an  Osprey's general flight path. The birds will follow the sun, stars, and coastline of North  American to the tip of Florida where they cross the Straits of Florida to Cuba before

flying east to Haiti and the Dominican Republic. From the Caribbean, the juveniles undertake a fly 500-mile open water crossing to winter in South America. The juveniles  chose fish-filled waters along rainforest rivers and lakes into the Amazon Basin ranging  from Venezuela and Columbia to Brazil. Adults tend to winter farther south with adult  females nesting as far south as Argentina.

It's a 3,500-5,000 mile journey, depending on the route the juvenile takes. Many  dangers face during the fall migration. These first-time migrants have deadly collisions  with cars, ships, or power lines and are shot by subsistance aquaculture farmers for  poaching fish. These young-of-the-year birds can be blown off course by severe storms  and hurricanes or get lost in open-water crossings. However, the juvenile Ospreys that  do survive their first 18 months year have a better chance of living through future  migrations. The Class of 2021 should return to Cayuga Lake in the April of 2023. The 

new males will look in this general area for places to nest while the females look for  mates within a 100-mile radius of their natal nest.

Blog #430 Is It Legal to Tear Down an Osprey Nest?

Nearly every spring outraged birders tell me about Osprey nests they have seen torn down by NYSEG (New York State Electric and Gas). How can this be legal? Don’t the Migratory Bird Act of 1908 (MBA) and the Migratory Bird Treaty Act of 1918 (MBTA) protect migratory birds, including their nests, eggs, and chicks? The 1908 law and its hundred years of treaties was the foundation of the America’s conservation legacy, that is until Trump came to town. One of his first moves was gutting the MBTA: industry benefited and the environment lost. Much of the MBTA has been reinstated, although there are still serious loopholes favoring industry by permitting "incidental takes" or animals unintentionally captured, live or dead, during industrial operations.  An Osprey nest is considered active if it contains viable eggs and/or chicks. A nest becomes active when the first egg is laid and remains active until fledged

Blog #397 Halfway Mark: Three Weeks

  On Osprey Time On Osprey Time just moved to blogger.com. Pardon the delay in posting.  Please bookmark! A mother feeding her 3.5-week-old offspring, courtesy of Cynthia Sedlacek.   Three and a half weeks into the nestling period, the three chicks have grown halfway to their adult size with Moana, the eldest, weighing just shy of a pound. Full-grown adult males usually weigh 2 pounds and females can be up to 4.4 pounds. Sleeping through most of the day and all night, the pile of offspring springs to life whenever their father, Orpheus, brings a fish to the nest. When awake, the nestlings waddle around the nest with their enormous feet, defecating over the nest edge, and peering over the rim at the people below. They are starting to use their wings for balance and rock forward on them to get a good stretch. When it’s mealtime, the eager chicks make their way across the nest to get fed by their mother Ursula.   Once their crops (storage organs; see second photo below) are full of food,

Blog #461 Sneak Peek at Osprey Season 2024

  Orpheus (L) and Ursula at their Salt Point Nest March 26, courtesy of Cindy Sedlacek. The following is a sneak peek at what this Osprey summer will entail. Our northeastern Ospreys return to their breeding habitats just after the early spring thaw. This year’s first Osprey was seen in Cayuga Lake Basin on March 15, an early date many attribute to  the mild winter. Most nest occupants will have returned to their nests and reunited with their mates by this weekend. These returning Ospreys have just completed their 2,000–4,000-mile migrations from their wintering areas along the coasts of South America and in the wild Amazonian tropics. The range of landscapes that a cosmopolitan Osprey can experience in its lifetime is staggering. In general, the older breeding males arrive on their nests followed by their mates in a few days. After that first wave of older Ospreys arrive, unmated adults and second-year birds migrating north for the first time after spending two years in the South, wil
