Courting Great Blue Heron Pair at SouthCoast Rookery

Great Blue Herons swoop through the air with blitheful grace, so unexpected for such a large and seemingly awkward creature.  Yet, if aerial ballets amaze, their Geisha-like courtship movements atop the trees precariously balanced on teetering twigs stuns the senses. 

In this early stage of seasonal courtship as pairs return to the rookery and before preparing the nest for this year’s chicks, ritual behavior ensues each time the male returns to the aerie.  Loving tenderness is expressed in elegant poses so gentle, so sweet and so dramatically effective.

Courting Behavior as Male Great Blue Heron Returns to Nest

When the greeting ritual ends, the mating pair begins a grooming phase with the same loving tenderness as demonstrated below.

With the courting ritual temporarily behind them, they can refocus on preparing the nest for eggs, incubation and chicks.  The next two months will be a busy time for this pair.

Yet, even in the busy-ness of nest preparation, there’s always time for a gentle peck to reinforce the couple’s bond.

Pterodaytls in Flight — Great Blue Heron (Ardea herodias)

Great Blue Herons in flight resemble nothing so much as the reincarnation of ancient pterodactyls.  They are magnificent creatures that cruise through the sky with lumbering grace.  Their raucous squawks and “kronks” add depth and breadth to the simulation of prehistoric mystery. 

Turtle Journal offers the following montage of Great Blue Herons in flight for your pure enjoyment.  Each image can be enlarged by clicking.

Osprey Arrives @ SouthCoast Rookery, March 23rd

The first osprey (Pandion haliaetus) arrived at the SouthCoast rookery in Marion on March 23rd.  Circling above the pond and swooping between the trees, the osprey evoked a riot of squawks from nesting pairs of great blue herons (Ardea herodias) who had glided into the rookery two days earlier on March 21st.

Osprey Promptly Evicts Blue Heron Pair from Prime Nest

The osprey immediately and unceremoniously evicted the early great blue heron pair from the prime nest in this rookery, repeating what had occurred in 2012 and 2013.  (See Aggressive Ospreys Evict Great Blue Heron Nesting Pair.)  Perhaps fortunately this year, the eviction happened before egg laying had begun.  The 2012 eviction took place in early May!

Ospreys and Blue Herons Do NOT Make Friendly Neighbors

As each species takes flight from its respective nest and nears the other, cacophony and chaos ensue.  Turtle Journal observes, “Isn’t Nature grandly harmonious?“

Great Blue Heron Returns to SouthCoast Rookery (March 21)

Blue skies, a stiff breeze and chilly temperatures greeted the first Great Blue Heron (Ardea herodias) who returned to the SouthCoast rookery this morning, March 21st.  Soon followed by its mate, the pair naturally took residence in the best nest within the rookery.

SouthCoast Great Blue Heron Rookery

The Turtle Journal team has been following this major Great Blue Heron rookery on the SouthCoast since Spring 2012.  Many pairs of Great Blue Herons compete in sometimes open battle with several pairs of Ospreys (Pandion haliaetus) to raise their young in this perfect, well protected nursery habitat.  (See Great Blue Heron Rookery on Massachusetts SouthCoast.)

Great Blue Heron Occupies Disputed Nest

The Great Blue Heron pair this morning assumed occupancy of the best and most disputed nest within the rookery.  For the past two seasons, ospreys have evicted Great Blue Heron pairs from this nest.  (See Aggressive Ospreys Evict Great Blue Heron Nesting Pair.)  It will be interesting to observe whether the battle continues this year.  For the nonce, though, with no ospreys in sight, Great Blue Herons are in charge.
