Warm day for some Spring Birds

One of the advantages  of my job is being able to get out "in the field" every now and then.  Today I had to walk a very large site which may potentially be developed as a solar farm as well as check out a piece of Open Space to ensure no dumping has occurred, check on the status of the vegetation and see if I could spot any new species for that location.  As a bonus, I was able to go visit the Bald Eagle nest at lunch - though it was probably 10 degrees cooler down by the water!


The first site wasn't too thrilling - very thick woods.  I wasn't expecting to see anything, especially this early in spring but there's always the potential for nesting owls or a fox den, however the habitat isn't quite right for fox (at least where I walked).  I did hear one distinct call - a very notable trill but couldn't figure it out.  As luck would have it, a friend of mine posted a video on facebook later in the day with audio of the same call, and with the help of others we determined it to be the aptly named Pine Warbler.  Reading this blurb from Cornell's website certainly confirms this is the bird I was hearing:

The best way to find Pine Warblers is to narrow them down by habitat and voice. Head for a pine forest in the eastern United States (check a range map for specifics), and then listen for a clear, steady, trilling song. Chipping Sparrows and 

Dark-eyed Juncos sound very similar and can occur in the same habitats, so be aware you might find these birds instead. Pine Warblers tend to stay high in pines and can be obscured by tufts of needles, but a bit of patience is likely to be rewarded.

When I got to the second site (AKA lunch spot) I enjoyed a sandwich waterside while observing the osprey on their still shabby looking nest.  One of the birds brought some nesting material before disappearing and I could see an Eagle on the nest in the distance.  After lunch I observed the Osprey fiddling with some twigs in the nest, adjusting their position.  It's really incredible to look at the construction of these things and imagine them being put together by talons and beaks.  I spent quite a bit of time scanning the surroundings my new Nikon binoculars - but couldn't locate the "Adult" Eagle anywhere.  It was confirmed that it wasn't anywhere near me when another pair of osprey (I believe nesting to the west of the Eagles) soared high in the sky chirping very loudly.  If the Adult BE was around it probably would have made its presence known.

Since the tide was low, I was able to take advantage of a spit of sand that juts out into the creek which was covered with just a couple inches of water.  My new waterproof Salamon hiking shoes (which I bought for an upcoming trip) worked as advertised - submerged in about 3 inches of water and not a drop on the inside.  So much better than lugging some overshoes or wading boots around... As I scanned the marsh again (where I saw the Eagle on Friday) I watched as 4 Great Blue Herons landed.  I thought this to be odd, because aside from maybe seeing two together in a marsh, I'd never seen these birds together (especially not flying together).  A quick check of Cornell's website shows that
these birds are solitary except when on migration - so there you have it!

I re-located the two Osprey - busy preening on a snag across the creek, near the Eagle nest.  Not sure if this was intentional or not, but likely making their continual presence and "ownership" of the area known.  With my lunch break over, I headed out to a property known as "Pheasant Meadow" which Brookhaven Town purchased in conjunction with Suffolk County and preserves as a meadow habitat. The property has a wide variety of wildlife (I'll include the list I've made later if I can remember to find it) and is a unique habitat worth talking a walk through if you're in the area.  I wouldn't be surprised if Eagle's began nesting on the southern tip (known as Haven's Estate) within the next 5 years due to the habitat and location.  While wildlife wasn't terribly abundant here - I did see one raptor though couldn't ID it and spent a few minutes photographing the very active Tree Swallows, including 1 who was very curious about a nest box that the Eastern Long Island Audubon Society (ELIAS) had erected.

I love when an opportunity like this presents itself.  With more time and my tripod I could have gotten the "perfect shot" but I'll take what I got considering.  Whenever a bird returns to a perch consistently, and you have good lighting behind you - you pre-focus your camera and wait until the bird approaches before firing off shots.  Sure, 9 out of 10 will be terrible, but sometimes you get lucky!  With at tripod and a remote trigger, this is really easy because you don't have to hold the camera and have both eyes available to see when the bird comes back to the perch.  I hope to try this again sometime soon with even better results.

As my time int he field would down I got two new birds for the property on my way out - a Northern Flicker and a Purple Finch.  And lastly I heard a rustling that I knew I wasn't responsible for and looked down to find this little guy:

Cold and Wet Observation - Nesting Eagles

(Excuse the terribly quality of these images - the bird was crazy far away and with overcast skies AND rain, well... you get the "picture").

I was off from work yesterday and knew it would be very windy today so I thought I'd take the trip to see the Bald Eagles at WFE again yesterday.  A friend of mine had been down a bit earlier but didn't see anything of interest (don't think he saw both, just the one on the nest).  When I arrived, a few birders were there with spotting scopes, but it looked like they were packing up and getting ready to leave.  When I walked out to the creek I felt the very cold wind and realized this wouldn't be that fun. After searching for the Eagle that wasn't on nesting duty and locating it about 1,000 feet away on the marsh, I went back to my vehicle to get a spotting scope and my Marmot Men's Precip Jacket and headed back out to the marsh as the rain began to fall.  

Aside from some duck flybys, nothing was happening.  As I looked out on the marsh at the Eagle I observed a number of corvids (crows - but I couldn't tell if they were all American crow or if some where Fish Crow so let's just call them corvids) congregating near the eagle in addition to some Greater Black-backed gulls (which are huge by the way - the largest gull species in the world as a matter of fact and having a maximum wingspan just shy of a male Bald Eagle).  What surprised me was the Eagle's complete lack of concern about these other species and vice versa.  Typically, raptors are magnets for murders of crow or marauding blue jays.  Red-winged black birds frequently chase and harass Osprey and conversely large raptors often scare away other species of birds.  This is not the case with this Bald Eagle (and I presume many Bald Eagles - though I have very little observation time to back that up) as it seemed completely content with its present company.

After spending some time in the rain observing the eagle as best as I could (the spotting scope was not terribly secure and the wind was relentless (good thing I don't get seasick!) but I observed a few instances of Crows walking right at the Eagle, as if they were trying to get a reaction from the much larger (and deadlier) bird.  But the Eagle was having none-of-it and remained on its perch (which after looking at the images turned out to a stick - which I couldn't see from my vantage point).  At one point, a Greater Black-backed gull came in very close and instead of intimidating the gull with its massive beak or turning its talons to the bird, it simply twisted its head and gave the gull a nonplussed expression - as if it say "Really? There's a whole marsh here!".

As the rain got more intense and my hands got colder (should have brought gloves), I heard the unmistakable chirp of the Osprey (which to this point had not shown up and had not been observed on the "nest" as it was last time I was down there.  The Osprey flew very near the Eagle Nest, calling out several times which I thought for sure would bring the adult BE over from the marsh to drive the bird away.  But the Eagle stayed put (certainly visually aware of what was going on, and hearing the Osprey chirp away), perhaps figuring it wasn't worth the effort unless the Osprey really started to harass its mate.  The Osprey then turned down the creek and patrolled the marsh (possibly looking for fish below) and I wondered if it would go after the Eagle which has been so tolerant of the other birds.  Sure enough, the Osprey slowly got closer and closer until it swooped down at the Eagle.  The Eagle (as expected) flashed its talons and wings which not only pushed the Osprey back up but spooked the loafing gull.  I stuck around for a couple more minutes to see if the Osprey would come back - but it continued west probably in search of fish.  The Eagle remained on its perch, soaking wet from the rain, waiting things out until it was time to take over nesting duties and I returned to my car soaked (but only from the waste down - thanks Marmot!).

You can see the wing of the Gull that was sitting right next to the Eagle.  He got out of there real quick!

Today is far too windy to bother going down - and tomorrow will likely be too busy with family activities to make a trip.  I'm hoping to get there on Monday, if even for my lunch break.  I have decided to focus my efforts on this nest instead of the one I first documented (you can read about that one here if you haven't been keeping up: Bald Eagles are Back) as it's much easier to observe the actual nest and the location is geographically advantageous because the Eagles (and Osprey) must funnel past my location when fishing or returning to their nests.  Hope everyone has a great Easter / Passover weekend!  By the way - can you spot the Eagle in the nest??

Another Bald Eagle Nest

This year the number of confirmed Bald Eagle Nests on Long Island has doubled - and lucky for me, there are now three within 15 miles in either direction.  One is located at Wertheim along the Carmans River and is completely inaccessible (the Wildlife Refuge closes access to the creek so kayakers cannot approach).  The nest I have previously photographed and discussed in my last two posts has been protected with the closing of a trail that leads to it, as has the one I photographed today.

"Adult"

Sub-Adult

Todays nest is located at the William Floyd Estate (which is part of Fire Island National Seashore - the only National Seashore in the State of New York).  At this moment there is no public access to where I photographed the nest from and even when access does become available later in the season I am wary to post specific details as there is also an Osprey nest that will likely be disturbed every time someone goes to visit the Eagles.  It's obviously not a problem if the Ospreys get annoyed a few times - but if there are daily visits with large groups not only does it stress the Osprey - it may cause the Eagles to unnecessarily chase / harass the Osprey.  

Ok, with all of that out of the way - let's get to the fun stuff!  I visited the site today around 11 AM (when it was low tide - allowing me a little closer access to the nest which is still about 500 feet from where i was standing) for work and hung out for a bit.  I saw the "Adult" (more on that in a bit) Eagle lazily go after the Osprey a few times and from the photos it appears that it brought some nesting material back at one point.  After maybe 30 minutes of being there, the "Adult" took over nesting duties and the "Sub-Adult" flew to a nearby perch.  It did a nice fly by (again, lazily going after an Osprey) and eventually headed north up the creek until it was out of site and I was out of time.  The photos of the two birds clearly illustrate why one is an "Adult" and one is a "Sub-Adult" as the one without the white head exhibits plumage seen in birds that are between 3-4 years old.  While Eagles generally don't reach sexual maturity until their 5th year, some do achieve it earlier which appears to be the case with this bird. Below: The first image is the "Adult" the second is the "Sub-Adult"

After work, I headed back down there to take advantage of the evening light.  The previously lone osprey was now joined by its mate - and when I first arrived I saw the Adult BE flying low over the marsh - but quickly lost track of it.  After awhile, one of the osprey headed up the River and the adult BE took off after it... The sun setting in the sky made for beautiful light but it was hard to tell what was going on - at one point I thought I saw something fall from the Osprey's talons, but hadn't seen it catch a fish so I was unsure.  After looking at the images, it's clear to me that the Osprey had indeed caught a fish and the Eagle was trying to steal it, however the fish dropped from the sky (presumably in someone's yard) with the Eagle continuing to go after the Osprey.  

Hard to see, but there's a fish!

Dropped fish falling underneath the Eagle

Watching this was a great experience and a notable difference from what I saw at the other Eagle nest.  When watching the Eagles and Osprey interact there - it appeared that the Osprey were trying to defend their territory and continually antagonize the nesting eagle being the aggressor.  But today, when the Osprey had a fish, the Eagle became the aggressor and tormented the Osprey until the Osprey gave up its catch.  Right after this exchange, the Osprey's mate came down the creek and the two birds landed on their nest - providing me with some awesome photo ops, with the Adult BE sitting on a tree on the other side - keeping an eye on myself and the Osprey.  

As the sun got lower and the day got later, I had to pack up and leave.  I took one last shot of the nest and realized I could actually make out the Sub-adult BE's head which was a nice surprise.  The other nest location is further away and the nest is constructed in a live pine - completely obscuring views of what is going on.  Assuming these birds are successful (which is a big assumption based on the lack of success from other nests on the Island in the past few years) we should be able to have a pretty good view (with binoculars anyway) of the babies as they grow.
