Three nestlings produced at the Osprey Cam nest are banded for future tracking!
by Ben Wurst, Habitat Program Manager
In the late afternoon of June 24, 2014, I kicked off the 2014 Osprey Nesting Surveys by banding the three nestings at the Osprey Cam nest. I was joined by Ann Marie Mason Morrison, with Friends of Forsythe NWR, our founding partner with the Osprey Cam, and two U.S. Fish and Wildlife Service interns, Jessie and Kirsten who helped bring out all the equipment needed to the nest (two 20′ ladders).
This is one of the most difficult nests to reach in all of New Jersey! It either takes a boat (at high tide) or two 20′ ladders (at low tide) to cross a 15′ wide ditch on the coastal salt marsh. Anyone who has crossed the ditch can attest to how difficult it is. Now you can watch and see what when into banding these three nestlings. A portion of the video was cut when I was attempting to repair the sound at the camera equipment box. At the same time the nest was cleaned of harmful plastic debris that the birds used as nesting material. A total of 3 balloons and a plastic bag were removed from the nest. The three young were banded with USGS bird bands (1088-04358,59 & 60) for future tracking. Check out a photo that I got of “the runt.” Enjoy!
First egg was laid on April 19.They were incubated for 38 days, which is slightly more than the average of 35 days in NJ.The first two eggs hatched on May 29th, and the third on June 1.5-7 days old. Sleepy…Feeding time is non-stop with ospreys!Downy and body feathers start to emerge at 14 days old.Today marks 21 days old (for the oldest two young). They’re now very active in the nest and like to check out all the cool nesting material mom & dad used in the nest.
Three eggs have hatched at the Osprey Cam nest at Forsythe NWR in Oceanville.
It’s been a hectic spring (to say the least). I’ve been swamped with field work since early April. Time has been flying by!!
The osprey pair nesting at the nest with our Osprey Cam on it has successfully hatched three young. The eggs hatched at ~37 days and in the order they were laid. Ospreys exhibit asyncronous hatching, which helps make sure that only the strongest young survive to fledge. In years with a good supply of fish then all young will survive. When there is harsh weather or a lack of prey (fish) then the oldest and strongest will survive, this is often called natural selection. The last two catches, from the male, have been very large white perch. There has been so much food that the young all get their fill. Sometimes the runt won’t get fed right away, but if he peeps a lot and begs for food, then he will get his share too.
Regarding the trash in the nest:
We are watching the plastic in the nest and will take action if necessary to remove it. Our policy is only to act when a bird is in a life threatening situation. Us entering a nest creates disturbance which might cause even more harm (more so when a bird is potentially entangled). Extreme care (and patience) must be taken in these types of situations. Trust us. We’d LOVE to not see the trash in the nest, BUT this is a teachable moment for all who are watching the Osprey Cam. Please share our post on social media and encourage your friends to pick up the next piece of litter they see or to not release balloons! If we all act, then we can all make a difference!
The osprey pair at our Osprey Cam nest has been “decorating” their nest with plastic marine debris. They’re turning out to be hoarders of plastic mesh bags. So far they’ve collected three to use as nesting material. How will this play out? We can’t say for sure but are closely monitoring with the Osprey Cam.
The ospreys returned and so did the marine debris.Yay! Some natural nesting material!!Too many plastic mesh bags!!They’re slowly migrating out of the nest…
The extreme cold weather in January brought some really neat winter scenery to the coastal saltmarsh. One of the most productive ecosystems in the world is almost totally desolate in the middle of winter. There are still a few signs of life though, which have been captured by our Osprey Cam, including top tiers predators, peregrine falcons, and herbivores, snow geese. There’s no doubt that each plays a role in the ecosystem. The snow geese eat any kind of vegetation that they can find and they consume any part of the plant, seeds, stems, leaves, tubers, and roots. The osprey cam showed them sticking there heads underground to forage on the rhizoidial roots of saltmarsh cordgrass (Spartina alterniflora). Here’s an interesting fact from Cornell University’s All About Birds website: “Food passes through the Snow Goose’s digestive tract in only an hour or two, generating 6 to 15 droppings per hour. The defecation rate is highest when a goose is grubbing for rhizomes, because such food is very high in fiber and the goose inevitably swallows mud.” Their droppings will no doubt help to fertilize the marsh in the spring!
Ice floe.A few adult peregrine falcons have been perching on the platform.Snow and geese.More snow geese…YUM! Roots and tubers!Got a napkin?Looks like the arctic…6″ of fresh snow.
This morning a pair of peregrine falcons have been hanging on the osprey cam nest at Edwin B. Forsythe NWR. First a female was perched on the nest, then she flew off a couple times, only to circle around and land on the nest again. Then a male landed on the platform and was seen calling out, most likely to the female. We’re not sure if they are a breeding pair or not. The female only had a silver federal band on her right leg and the male has a black federal band (which means he’s a Jersey bird) and a black/green auxiliary band on his left leg. It is unreadable since it’s pretty covered in dirt/mud. By the looks of him it looks like he just finished breakfast…
Last week we set out to finally repair the osprey cam at Edwin B. Forsythe NWR. (Note: we do all of the technical repairs and maintenance to the camera system) Initial repairs were delayed to protect the osprey young. Timing restrictions are set in place to reduce disturbance to nesting ospreys and nests cannot be disturbed from April 1 – August 30. This is a good thing! When we finally set out to figure out the issue with why the camera suddenly lost power, we had to wait until it was safe to enter the nest. When we first went out (August 15) for a quick diagnosis (after we knew all young were flying and not relying on the nest as much) and got the cam online again…but it died after 30 minutes of streaming…
We went out again in late September and determined it was the solar charge controller but had to wait to get a new one. In October we went out out to replace the charge controller but the system was still down and the equipment was not getting power. The two batteries only had 6 volts of charge and needed to be recharged. So, the two 50lb. batteries were lugged a pretty long distance and charged up. Once they held a charge we made plans to go back to re-install them and hoped it would work. Success!! The batteries powered up the system and within minutes the camera was streaming online!
Special thanks to volunteer Joe Bilotta for helping out with the re-installation of the batteries!
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?
Single use plastic bag wrapped around ospreys neck…
by Ben Wurst, Habitat Program Manager
We had quite a scare last week, on April 30th around 12:30pm, after getting a report from an observer of our Osprey Cam on our Facebook page. A single use plastic shopping bag had gotten wrapped around the neck of the incubating female. After getting the report we started to monitor the situation to see how it would unfold. The bag was loosely wrapped, so we hoped she would be able to free herself…which she did after an hour.
Here you can see the single use plastic bag around her neck.
A lot of viewers and FB fans were asking why we weren’t going out to remove the bag from her neck. We answered each and every question to help make sure people knew that we were doing everything we could to protect her safety. First, we couldn’t just walk out to the nest (which is out in the middle of the salt marsh) without the female reacting to us and flying off the nest (with the plastic bag around her neck). Her flying off the nest with the bag around her neck would have only caused even more harm to her. She could have gotten snagged on a piece of nesting material and in the struggle could have choked to death or she could have fractured one of her eggs… Second, if she would have been tied down to the nest, then we would have enacted a plan to go out to the nest (after a certain amount of time) and released her. Our policy is that we will only intervene if it is a life or death situation. When we enter their nest sites we introduce stress to the birds which can ultimately do more harm than good. Finally, at least we have a camera to monitor the nest! Think of all the other 500+ nests in New Jersey where we only go out to monitor them once or twice during the nesting season. So much plastic winds up in osprey nests that it is a serious concern. People need to be more aware of their surroundings and do their best to make sure waste is properly disposed of.
There are ways you can help make a difference:
Reduce the amount of stuff you buy and the amount of trash you produce
Reuse what you can, recycle what you can’t
Pick up litter when you see it. There is a great movement in Australia called “Take 3” and their message is simple: “Take three pieces of rubbish with you when you leave the beach, waterway or… anywhere and you have made a difference.”
Stop or reduce your dependence on single use plastics
Use reusable shopping bags
Don’t release balloons!
The female struggles to get free of the bag.
Statistics for plastic recycling are dismal… According to the U.S. Environmental Protection Agency “In 2010, the category of plastics which includes bags, sacks, and wraps was recycled at almost 12 percent.” We’re lucky that she was able to free herself. This just proves that ospreys do not have an easy life. There are many threats to ospreys and they have very high mortality rates, which are around 80%.
On the positive side, the female and male continue to incubate three eggs at Edwin B. Forsythe NWR. We should start to watch for hatching around May 19-20th. We have been writing nest news with other life history information on a weekly basis on our Osprey Cam page.
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!!
