Hatching!!

Three healthy hatchlings at Forsythe NWR!

by Ben Wurst, Habitat Program Manager

Chicks!

If you haven’t noticed, we now have three healthy osprey nestlings at the nest at Edwin B. Forsythe National Wildlife Refuge in Oceanville, as viewed by our Osprey Cam. The first chick hatched on May 25th, the second on the 26th, and the third on the 28th. The eggs hatched in the order they were laid, referred to as asynchronous hatching. The incubation period was ~38 days for all three eggs (average is 35-37 in NJ; 32-43 throughout their range). With the cooler temperatures the longer period is expected. Osprey young are born semi-altricial, or are downy and require close parental care to survive. The male osprey has been very busy foraging and catching more prey to feed all the hungry mouths. Have you tried to identify the prey that they’ve brought in?

Ospreys are back!!

Meet the osprey pair at Nest #2835

by Ben Wurst, Habitat Program Manager

I must admit, I’ve been anxious for the return of this pair of ospreys (and all others for that matter). The return of ospreys is a sign of spring, regrowth, and of recovery (from the effects of Superstorm Sandy) as we watch them rebuild their nests as we have helped to repair and replace many of their nesting platforms throughout our coast.

Over the past 6 weeks I had the task of installing a new remote/solar powered/high definition camera system on the coastal salt marsh of New Jersey. The camera system was installed inside Edwin B. Forsythe National Wildlife Refuge in Oceanville next to an existing osprey nesting platform. The camera system streams live video 24/7 from the nest to the Visitor’s Center at Forsythe and on our website. Since the system has been installed we’ve had crows, peregrine falcons (one that was a juvenile who was ID’d by her leg band and originated in Delaware), and a great horned owl (not good since owls are predators of osprey young) perch on the platform.

The nesting pair of ospreys arrived back from their wintering grounds on Friday, March 29th. We don’t know anything about the breeding pair other than neither is banded with USGS bird bands. The female has a very heavily streaked and prominent “necklace” of brown feathers on her breast. The male is  smaller and has a bright white breast. Since arrived they have already been copulating (breeding) on the nest and will continue to do so over the next few weeks until the female will lay eggs in late April. For now they will continue to spruce up their nest and the male will perform courtship displays, after a successful hunt or while carrying nesting material, near the nest to help strengthen their pair bond.

There is a microphone out at the nest and it works. Some issues have come up with pairing the sound and video feeds and we are working on getting that sound online. I will be writing a weekly “Nest Cam News” journal on the Osprey Cam page with information about osprey reproduction, life history and other cool facts about ospreys! Some other great news is that the Wildlife Drive at Forsythe NWR will be open this weekend!!

By now most ospreys are back from their wintering grounds in Central and northern South America. Generally the older more experienced birds return first and the younger inexperienced adults follow. Over the past month I’ve been very busy with platform repairs and installations throughout coastal New Jersey. You may not be aware but I maintain a huge number of nesting platforms. In just the past couple weeks I’ve worked as far south as Avalon (where I lead a group of students and their parents from Collingswood to replace an existing platform) and as far north as Bayonne (where I installed 3 platforms with local middle and high school students). Both were memorable experiences for both myself and many of the students. Most of them had never been on a boat or ever had the chance to walk on the saltmarsh.

Maintenance of existing platforms is critical to the continued recovery of ospreys. Over time (and in some cases, not much time) the condition of these nesting platforms is degraded, mainly by the environmental conditions where they’re placed. For the most part the fasteners are what go first from contact with high levels of moisture in the air, after that,  the wood decays (unless a pressure treated or cedar wood is used). One way to help prevent the decay of platforms is to use marine grade stainless steel screws, galvanized bolts, and treated lumber. If we were to lose a large portion of the available nesting platforms in a given year then the population would suffer, so it’s important to make sure existing platforms remain in good condition.

Last week I got out to the “Wildlife Drive” at Forsythe NWR in Oceanville to repair a platform. The platform top had lost a side and could no longer hold nesting material. I built a new top out of salvaged wood that I collect and installed it on Thursday afternoon. The next day a male osprey began to place nesting material in the freshly repaired platform. Talk about perfect timing!

If you’re interested in helping us to maintain osprey nesting platforms, contact me about our new program to “Adopt a Platform.”

Capturing peregrines in flight

Photos from the field while monitoring peregrines

The subject of peregrine falcons have hijacked this blog! On Friday, I visited a nest at Forsythe NWR to medicate the young for prevention of trichomonas, an avian disease carried by pigeons and doves. Adult peregrines can transfer it to their young and if not treated can kill them. Kim Steininger, a renowned and award-winning bird photographer joined me and got some amazing photos! While I was up on the nesting tower, Kim was stationed behind her camera, which was wielding a powerful lens to capture these amazing photos of the adult peregrines in flight while I checked on the nestlings.

This was my third visit to this particular nest. I can attest to the strong parental bond of this female to her young. During my first visit (5/21) she hit me while I was attempting to look for a parasitic fly that has caused hatchlings to die in previous years. The young were about 2-3 days old and were very vulnerable, so the aggressive nature is understood.

Peregrines and other birds of prey, like eagles, owls, ospreys, and hawks see humans as predators. This is because they don’t have any other predators in the wild. This is also why disturbance is a major issue during the nesting season. When an adult leaves the nest; its young are unprotected. They are susceptible to predators like gulls and crows. Never approach a nest and only view from established viewing locations!

On the second visit (5/24) the female landed on the nesting tower, not more than 5 feet away from me! In the nest 2 weeks the young will be banded with federal USGS bird bands and state bi-color bands for future identification.
