Bald Eagle, subadult, 3rd year

November 24, 2013 in Bald Eagle

While checking out many of the Eagle locations in Lawrence along he Merrimack River, encountered this subadult at close range.  For some reason it was not concerned about a nearby human presence with a big telephoto lens!  Looks like a third year bird based on markings and whitish head coloration and eye stripe.  Also, shades of yellow in lower bill and lightly in place on upper bill. Only able to view in the shade and not in direct light, but quite a treat all the same.  A few added photos posted:

Bald Eagle, subadult

November 21, 2013 in Bald Eagle

Another wonderful morning to observe the Bald Eagles along the Merrimack River in Lawrence!  Stopped again with a short time frame to look for Bald Eagles.  Observed one adult perched on a tree branch overhanging the river.  It may have reacted to my presence at a distance of 1,000 feet, and departed downriver towards Haverhill.  As it is flying away, another possible adult Eagle is seen perched on a branch farther away.  Binoculars confirm a second adult Bald Eagle.  Minutes later, a subadult comes cruising along the south side of the river hugging the edge of the tree branches and looking down.  As it proceeds to almost over my head, it notices me watching, and does an abrupt U-turn and heads down river.  Quite a treat!  This one looked like it may have a bill that is starting to turn yellow, suggesting an older subadult.

Made a quick visit to one of the Merrimack River access points to look for Bald Eagles with a few minutes to spare before going to work.  As I’m getting out of the car, the high pitched call of Bald eagles was heard.  Grabbed my camera to find to subadults practically overhead in playful looping flight almost too close to photograph.  Again, bright later morning sun and not great angles, but a number of documenting photos in order to analyze later to help determine approximate age of these two eagles.  More photos:  www.pbase.com/birdshots/image/153476131

What a week for Eagles last week!!  An adult on Tuesday, subadult on Wednesday, and then a five eagles on Thursday.  Two adults and three subadults were seen perched and flying around the Merrimack River in Lawrence.  What an amazing show and early in the winter season.  All this on the week that I depart on Friday for NYC to join our engaged 25 year old daughter for a concert at Madison Square Garden.  the band we were going to see: The Eagles!!!! WOW!  This adult was making large loops over the Merrimack River.

Bald Eagle, subadult – Lawrence

The next day, this subadult was seen just after noontime while flying over the Merrimack River in Lawrence.  It was flying slowly and then made a number of large loops.  It was a challenge to see as I was looking into the bright sunshine.  However, wanted to post this to document another November sighting.

Bald Eagles around the nest!

June 19, 2013 in Bald Eagle

The Bald Eagle pair continue to watch over the eaglet as it grows larger each day.  Today provided an opportunity to join others and watch the eaglet flap around the nest and perch on a number of nearby branches.  An adult returned to the nest with more food and helped the eaglet with tearing the prey apart.  Another adult arrived and then, possibly a third came by the nest site for a short visit.  One of the adults circled around the nest a few times allowing for a series of flight shots in beautiful late day light!

Bald Eagle chick getting closer!

June 13, 2013 in Bald Eagle

Stopped by the Eagle’s nest Thursday morning under heavy overcast skies and found both an adult and the eaglet in the nest.  The adult had likely just returned to nest with some type of prey offering.  The eaglet spent some time eating and then flapping its wings while moving around the nest!

The Eaglet is closing in on fledge date!!

June 9, 2013 in Bald Eagle

The eaglet is closing in on the fldge date!  According to Birds of North America, nest departure can occur at 8–14 wk. Variability in departure date related to effects of sex and hatching order on growth and development   Adults may “encourage” nest departure by flying around nest with prey item vocalizing when young are hungry.  Fledglings may continue to use nest as feeding platform for several weeks as they gain flight and foraging skills.  Juveniles continue to grow and develop postfledging.  Mass may actually decrease or remain stable postfledging, depending on food availability and foraging ability of individual. Skeletal growth and development minimal postfledging. Muscle mass continues to develop and flight feathers fully emerge. Little data on when growth is complete in immatures.  Fledglings follow adults and may be fed by adults up to 6 wk after leaving nest

Bald Eagle chick feeling the heat!

May 30, 2013 in Bald Eagle

Young eaglets grow rapidly and may eat up to two pounds of fish per days!   Eaglets are fed a steady diet of fish, occasionally supplemented by water fowl (ducks, geese) or water birds (gulls, cormorants).  About 85% of a chick’s diet will typically consist of fish such as carp, white sucker, shad, bullhead and sunfish.  The adults capture and tear the fish into small strips, offering them to the chicks. The chicks snatch the food from the adult’s beak and swallow it whole. An eagle chick will eat as much as it can at a single feeding, storing food in its crop. The crop, an organ located near the base of the bird’s neck, will enlarge as it fills, resembling a golf ball.  About ten weeks after hatching they begin to make short flights from the nest spending much time with the parent birds observing the adults as they find, cathc, and eat food.
