Bald Eagle nest: Essex County

March 7, 2017 in Bald Eagle

_W7I3326-001This new Bald Eagle nest may well be used for the first time in 2017.  The nest was completed in the fall of 2015 and the Eagle pair spent a great deal of time around the nest in the spring of 2016.  But it appears that no eggs were ever laid.  This “playing house” is not unusual among  a newly formed pair of Eagles.

It has been stated for many years that a Bald Eagle pair will mate for life, but if one partner dies, or disappears, the other will if lucky find another mate. A newly bonded pair may work several years on a nest before actually breeding. They may desert one nest site and start again somewhere else, usually within 1/2 mile. In Eastern Massachusetts, bald eagles will begin to nest sometime in February or March.  Each nesting pair will spend a great amount of time preparing the nest before any egg is laid. The successful nest is generally located in a large tree, within one mile from water, either a lake or river, where adequate food is available.

Bald eagle nests are generally found from (50 to 120 feet) above the ground, in a tall, sturdy tree. It takes at least two weeks for a pair of eagles to build their nest.

A typical bald eagle nest will range from 6-10 feet in diameter and about 6 to 10 feet high. The nest cavity, where the eggs are laid, will be about 12 to 16 inches in diameter and about 4 inches deep.

A pair of eagles, once established, may use the same nest several times over a period of years. Each year more materials are added to the nest, which increases the size of the nest each year that it is used. Nests weighing up to 2 tons have been found.  Stay tuned!

Bald Eagle: Merrimack River, Lawrence

_W7I2553-001Always be on the lookout as you pass favorite locations, cuz you just never know why you might see!  For the past many years, Bald Eagles have been seen perched along the Merrimack River across from the NX Stage inc. corporate headquarters on Merrimack Street in Lawrence.  But since the recent park went in the Bald Eagles have for the most part avoided this location as a popular winter perch.  On this bright sunny Monday morning, it was a wonderful surprise to encounter this adult Bald Eagle perched and enjoying the morning sun overlooking the Merrimack River!

_W7I0547-001While driving along the Merrimack over this morning, discovered a Bald Eagle perched in a tree overlooking the river.  It is close to a possible new second nest location nearby.  Bald eagles build their nests in large trees near rivers or coasts. A typical nest is around 5 feet in diameter. Eagles often use the same nest year after year. Over the years, some nests become enormous, as much as 9 feet in diameter, weighing two tons.   A nesting pair will build a new nest if they feel threatened. Essentially, it’s not uncommon for eagles to build more than one nest within their nesting territory.  Eagles are very territorial during nesting season. They will keep other eagles out of their own nesting territory, which is usually one to two square miles.

_W7I0466-001A dark overcast morning with visibility limited to under 2 miles with fog, mist and temps in low 30’s.  Went looking for Bald Eagles along the Merrimack River and was very pleased to locate a probable nest with an adult perched adjacent to the nest.  Just a 1/2 mile away was a dark juvenile perched on a snag overhanging the Merrimack River.  Hopefully this will be an active nest this year!

_W7I0415-001Today started off as a dark morning with winds from NE at just 10 MPH, light snow, visibility about 1/2 mile and temps around freezing.  Made a pass by the ballfields in Lawrence next to the Essex Correctional facility and spotted an adult Bald Eagle.  It was perched in a large tree just east of the water treatment plant.  Nice views over the Merrimack River from the elevated ballfields.  No other Eagle in sight and no clear sign that eagle had leg bands.

_w7i6422-001Nice looks on cloudy morning at pair of perched Bald Eagles on a branch overlooking the Merrimack River.  They were seen from the Lawrence side of the river from the ball field next to the Essex County pre-release center and were perched on the North Andover side.  No ability to see leg bands, but likely continuing pair of local eagles!
