RE: [cayugabirds-l] Cayuga Lake bird sightings while kayaking

2014-07-26 Thread Bill Ostrander
Dennis,
 
We had a similar sized group of Common Mergansers on the Chemung River in
Elmira several years ago.  When I first saw them in early summer, the young
all appeared to be the same very small size.  At the end of summer, when the
young were nearly full grown, the count was the same.  The literature that I
read at that time referred to such a group as an amalgamated family with one
adult female and lots of young.  While my source stated that multiple
females may lay eggs in a single nest, it did not seem to attribute the
amalgamation to that, and considered the mechanism by which the amalgamation
developed to be unknown.  I think that the young associate with just one
adult female.

Subject: [cayugabirds-l] Cayuga Lake bird sightings while kayaking


On 23 July while kayaking on Cayuga Lake, my bird sightings included a Bald
Eagle, several ospreys, some double-breasted cormorants, a kettle of TVs
perched at the waters edge, and what appeared to be a single adult female
Common Merganser with a brood of 32 chicks in tow. One disadvantage of solo
birding is there is no one available to answer simple questions such as:  

1) According to allaboutbirds.org, Common Merganser clutch size is 6-17
eggs.  Are Common Merganser females known to combine broods and work in
shifts? 

2) Would a Bald Eagle that is disturbed during breakfast and drops its fish
from a tree and flies off, come back later to continue its meal? (I see at
www.baldeagleinfo.com/ that they also eat carrion, so I suppose coming back
to retrieve a recently caught fish would not be an indignity.) 

3) Would a kettle of Turkey Vultures be intrigued by a large zucchini
bobbing in the lake water a few feet from shore, wondering (from a distance
at least) if perhaps if it was a dead animal? (And does kettle refer only
to the airborne formation of TVs or can it also be used to describe a group
of TVs that is perching?  

Apologies for such simple questions,John

P.S. At the risk of being long-winded, here are a few more details regarding
the location and details of my sightings: 

I departed from Myers Point at about 7:30am, went a bit north of Atwater,
crossed over and kayaked down the west shore until Taughannock Park where I
followed a heading directly back to Myers Point, arriving there about 4pm.
There was a mild tail wind going north and a dramatic tailwind from abreast
of Milliken Station all the way back to Myers Point.

On the northerly, east coast leg of the journey, I spotted a Bald Eagle
perched in a tree perhaps 1.5 miles north of Myers Point. I watched it fly
out over the lake and dive close to the water and then circle back to the
same tree.  Having never seen a Bald Eagle fishing before, I assumed it had
missed its target when I saw no spray come up at the end of its dive.  By
that time I had my bins on the bird, but movement of the kayak prevented me
from seeing it well. Only when it was back perched in a tree and later
dropped its fish upon my approach did I realize it had caught one.

Rounding a point about half a mile south of Milliken Station, I was startled
as a TV look wing from about the water level and landed in a tree where two
or three other TVs were perched.  I believe there was at least one more
circling overhead.  On reaching a willow tree that was partly in the water
and where it seemed the TV had departed from, I found no carrion that could
have been of interest to the TVs, but there was a 16 long, 4 diameter
zucchini that was bobbing in the water a few feet from shore.  There were a
couple of half-inch nicks in the skin of the zucchini, but none seemed deep
enough to been the result of TV beak-work. 

As I recall the larger Merganser brood was between Cuddeback Point on the
Bell Station parcel and the Atwater/Nut Ridge Road area.

RE: [cayugabirds-l] Merlin food

2011-12-08 Thread Bill Ostrander
I sent this previously to Bob McGuire, but thought that it might be of
interest to others:

The one bird that I've seen Merlin catch was a House Sparrow. The Merlin
that our Audubon group saw last Saturday was hunting pigeons. It split a
flock in two and then cut an individual out of the flock and was pursuing it
when the two birds disappeared behind a building, so we did not see how the
action ended. Of course, Merlins seem to enjoy the chase even if they have
no real intention of catching the object of their pursuit. I even saw one
allowing four crows to chase it around our neighborhood. The Merlin appeared
to be flying slowly just so they could keep up. The pigeon chaser last
Saturday seemed serious and even experienced at dealing with pigeon flocks.

When I was an undergraduate many decades ago, I saw a Kestrel chasing a
pigeon near the bus station in Ithaca. On another occasion I saw a Kestrel
catch a Starling. In both cases it was winter, so maybe when food is scarce
these raptors take chances on hunting bigger, more available prey.

Somewhat related, an immature Red-tailed Hawk spent a winter in downtown
Elmira hunting the same pigeon flock that the Merlin was working on
Saturday. That same winter, an adult Red-tail spent a lot of time hunting
for mice on a nearby island in the river. I attributed that difference to
experience.

An article that I read about the expansion of Merlin into urban/suburban
areas in western Canada attributed their expansion to the availability of
House Sparrows.

Subject: [cayugabirds-l] Merlin food



Since it has been mentioned that Merlins taking mostly House Sparrows (no
one has ever mentioned starlings that I know of) is hogwash, I thought it
might be useful to look at the available data.  I copy here Appendix 1 from
the BNA Merlin account, which lists the results of 6 published studies of
Merlin prey selection, specifically to contrast urban and rural nesting
birds.  You make your own conclusions.

 

The BNA account summarizes those and other studies as follows, Most studies
report specialization on one or two locally abundant species of small birds.
Principal prey species characterized as: one of most abundant species in
area, often foraging away from cover making it vulnerable to predation, and
in 20-40 g weight range.

 

That seems reasonable, and suggests that the primary food will indeed vary
over space and time.

[cayugabirds-l] SFO Local Trip to Park Station

2011-05-15 Thread Bill Ostrander
Our group of four investigated Park Station, a Chemung County park about 3.5
miles southwest of Arnot Forest.  We first stopped at the fishing access on
Laurel Hill Road where two  adult Ring-billed Gulls were hanging out in the
parking area.  A transitional Common Loon was very actively diving, so we
decided to track down the singing Bobolinks in the flood control dam's
spillway and had fine looks at them, one landing just 10 yards away in the
mowed trail.  He joined two others to chase a female.  We watched the
flap-glide flight of Eastern Meadowlarks and listened to the buzzy songs of
Savannah Sparrows.  When we returned to the scope, the loon had finally
settled down and we were able to enjoy leisurely looks at it.  The six
White-winged Scoters that had been on the lake, Saturday, had already
departed, so Mallards and a passing female Common Merganser were the only
other waterfowl.
 
Next, we parked near the main entrance and headed for the woods.  Two
members of our group were beginners, so we took our time lookikng at birds
that afforded good veiws:  Chipping Sparrow, Yellow-bellied Sapsucker,
Red-eyed Vireo, Warbling Vireo, Yellow-rumped, Yellow, and Blackburnian
Warblers, Eastern Kingbird, and Tree Swallow.  Only I got to see the
Bay-breasted Warbler foraging in a Red Oak.  
 
We also spent time learning how to distinguish vireo, robin, and Scarlet
Tanager songs.  Early in our walk, we listened to the quiet song of the
Philadelphia Vireo, but only a couple of us got fleeting glimpses.  Other
songs that we spent time on included Black-throated Green Warbler, Ovenbird,
and a couple of the many calls in the Red-winged Blackbird repertoire.  A
Red-shouldered Hawk screamed from the forest as we were walking away from
it.
 
Everyone commented on the beauty of the place.  Unfortunately we did not
have enough time to explore it more.

[cayugabirds-l] SFO Sunday Local Trip

2011-04-10 Thread Bill Ostrander
The local SFO group was small with just three students:  Joan and Bob Horn
and Stephanie Herrick.  We spent most of our time at Dryden Lake and walking
a loop around the Jim Schlugg Trail, Keith Lane and Lake and West Lake
Roads.  We were able to compare females of all three merganser species.
Only the very distant Commons included any adult males.  Other waterfowl
included some Ring-necked Ducks, a single male Ruddy Duck transitioning into
breeding plumage, a breeding-plumaged Common Loon, and a near
breeding-plumaged Horned Grebe.
 
On our way to Dryden Lake the group discussed how to differentiate the
trilling bird songs and listened to junco, Swamp and Chipping Sparrows on
Stephanie's BirdsEye Pro.  We were glad to hear Swamp Sparrow singing in one
of the cattail areas at Dryden Lake.  As we walked in that direction, we
found a Brown Creeper calling and creeping in the grove of trees next to us.
After a patient search, we did locate the Swamp Sparrow who allowed all of
us to view him through the scope and see the field marks that we had already
discussed.  On the hillside beyond was a flock of Wild Turkeys and the
students noted that the one displaying male looked to have been through a
few battles this spring.
 
Our main finds of interest on the Jim Schlugg Trail were a little flock of
Golden-crowned Kinglets near our starting point and a Ruffed Grouse drum
about halfway to Keith Lane.  We did not encounter many birds on the
roadsides, but did enjoy watching a pair of White-breasted Nuthatches
stripping bark from a snag to take to their nest in a large tree cavity.  A
shrubby pond back at the park was full of barking Wood Frogs.
 
We used our remaining time up at Stewart Park where we added Bufflehead,
Lesser Scaup, Redhead, Gadwall, and American Wigeon to our day's list.
Stephanie spotted a small flock of swallows hawking insects toward the
lighthouse jetty.  The flock included at least a couple Tree Swallows, a
Barn Swallow, and two male Purple Martins.  When we went to the boathouse,
the Martins made occasional passes over the swan pen.  We also saw a Mallard
land high in one of the trees along the lake shore and Bob found a Wild
Turkey perched high in one of the trees along the channel behind the
boathouse.
 
Raptors were notably absent and we had to be satisfied withour two sightings
of individual Turkey Vultures on our way back to the Lab.

RE: [cayugabirds-l] Snow Geese and others

2011-03-12 Thread Bill Ostrander
Our Chemung Valley Audubon group was at Knox-Marcellus when all the Snow
Geese took off from the mucklands.  When we arrived at the Potato building,
there was only one Snow Goose to be seen, the one that four young hunters
carried back to their rendezvous point at the Potato Building.  It looked
like they were probably done for the day.  I asked them what the bag limit
was, and they said 25 per person per day, so they were short of their
combined limit by 99 birds.  It's going to take a long time to reduce the
population by hunting if every time one gets shot, the other quarter million
fly away.
 
We saw Jay, Tim, and Hope at Sheldrake.  I did forget to tell Jay one other
unusual bird we saw was a Red-shouldered Hawk perched in one of the bushy
trees far across the marsh due west of the visitors' center at the Refuge.

Subject: [cayugabirds-l] Snow Geese and others


Hi all, 
I went to north side of the lake, specially in search of Snow Geese. I was
not disappointed. Along the Drake Road, I found some tom Turkeys under usual
feeders.  Center Road was quiet except for couple of Horned Larks. But as I
was passing the road, I encountered my first flock of Snow Geese passing
over me heading somewhere along 34 B.  By the time I got the camera out, the
birds were gone. But I considered that as a good omen for things to come
ahead next. 
After a short detour on 90, I took my favorite Dixon road from Rafferty.
Nothing special but many robins along the road, a flock of about 100
grackles with a few Red-winged mixed in and a Kestrel. At the end of the
road I headed down to the lake, which comes out at Aurora Fire Station.
Along the lake north, I stopped at Factory Pond. As Bill noted it was devoid
of any ducks, but sleeping Screechie. At the same spot there was a very
entertaining Starling doing all kinds of mimicry including Meadow Lark. So I
spent some time with him trying my camera.
 
Next, I stopped at Cayuga Village road just off of 90. Here I encountered
huge flocks of Snow Geese flying overhead, which I found were heading to
other side of the lake as the lake was mostly frozen around this area. There
were many ducks but I did not spend time watching them as I was on an
assignment, so shot some B rolls. I went to the water's edge at Cayuga park
where I encountered Jay et al. 
 
Along Lake Road, I got a nice Common Goldeneye. Then headed to visitor
Center for a short stop. Then I headed to Mucklands via East Road. From East
Road, I could see huge flocks of Snow Geese in the muck. So I headed
directly there. From both sides of the road there were thousands of Snow
Geese and were just abut 300 mt from the road. I parked at the Potato
building and hid behind the building and watched and took shots (not with
guns but with a camera). I spent an hour or so when my battery died. 
When the whole group on the east side of the road rose, it made such a
swishing noise, it was soothing and hypnotic and amazing. Some took off and
other landed far side of the Muckland. As my battery had died, I wanted to
recharge it, so decided to drive to Carncrass road. While my batter was
charging on my car battery, I watched and took videos of Tundra Swans and
their behaviors. I just watched the shots on my TV and so many amazing
behaviors they seem to have. While I was there several thousands of Snow
Geese went north of Carncrass road, to feed I think. But watching them
