NESTING BALD EAGLE PAIR in SAN BENITO COUNTY, CALIFORNIA

MY HEART CARTWHEELS


Just about thirty days ago I arrived home from three months in the Southern Hemisphere. First thing I did was head to the BALD EAGLE NEST to check up on "Bob & Bernadette," as I named this pair. B & B were the first pair of Bald Eagles to nest in San Benito County, beginning in 2004. In the dimming evening light, I struggled to "see" the nest. Much had changed since my departure last October. Hillsides were green instead of brown, for one thing! However, I could not find the nest — and, the horror finally struck me — the 11 year old nest had become too heavy and the branches finally gave way! Last year, we estimated that the nest was 18 to 20 feet across and probably 10 feet deep. Each year, I've watched as B & B rebuilt the nest. They begin doing this in late October. So, when I left the country, all was well with the nest fully completed for (hopefully) another successful season.

Bob and Bernadette are considered an "advanced" couple  — tending the same nest for nearly 8 months of the year, every year steadily for 11 years. They lay eggs earlier than most Bald Eagles, even at this latitude. Consequently, the young hatch earlier. I
n all years, save one, they have managed to fledge not one, but two young. To date, they have successfully raised some twenty Bald Eaglets! This, in spite of the persistent drought. One reason for their great success is that they primarily rely on ground squirrels for food. (I confirmed this by watching for many hours). They do not rely on waterfowl, nor fish. 

The nest is on private property and the owners are well aware of it. A handful birders and locals know about the nest and have been extremely guarded about revealing the location. I cannot thank everyone enough for this. Some Bald Eagles are greatly disturbed by people and abandoned their nest. A big part of B & B's success depends on you, too. You know who you are.

For nearly three weeks, I've had a case of "empty nest" syndrome, missing them more than I thought possible. They were such a regular part of my life. I would see a Bald Eagle, and think that is was "Bob" or "Bernadette" — and, I was pretty sure. Like longing for a lost love, I'd drive through their valley home. Once I saw Bob sitting in a large tree, clutching a dead ground squirrel for half an hour. This raised my curiosity. Was he bringing food to Bernadette? There was no doubt in my mind that they would carry on, building a new nest, either this year, or next. However, the decades' long nest was so convenient for watching and such a part of my life. 

Last night I made the drive once again, hoping against hope. I was elated to see BERNADETTE ON A NEW NEST! My heart did cartwheels! The new nest is just about in the same tree, but is only about one fifth the size of the old, crashed nest. There is another nest in the tree. Perhaps, they built it first. From what I could tell, she appeared to be sitting on egg(s). She looked as though her head was tucked in and she was sleeping. I'm crossing my fingers on this and will return to check on things — practically, daily. (Okay, I get obsessed with them). My notes say that they were incubating on 20 February in 2013. So, timing is right. Stay tuned —

Many, many thanks to all who guard this nest! 
Happy Trails,
Debi Shearwater

IMAGES OF THE DAY by WILL BROOKS: FEBRUARY 22, 2015 MONTEREY BAY

Shearwater Journeys's leader, 16 year old Will Brooks, captured these images on our February 22, 2015 Monterey Bay seabirding trip. Will is a junior at Gunn High School and our newest leader, although he was not leading on this day, but simply enjoying the marine life with his dad who is also a birder. Will has been birding for eight years already — half of his life! He began photographing birds a year ago. Last summer he had the opportunity to enjoy Maine's seabirds through the Audubon Coastal Maine Bird Studies Camp on Hog Island. Will says that the camp gave him a chance to explore a small island covered with nesting Atlantic Puffins, guillemots and terns. He confesses to being fascinated and excited about seabirds.

WINTER SEABIRDING: MONTEREY BAY PELAGIC TRIP REPORT: FEBRUARY 22, 2015

BLUE SHARK

Howdy, Seabirders,
It has been a long time since we have offered a winter pelagic trip. This February 22, 2015 Monterey Bay seabirding trip was offered by Shearwater Journeys in conjunction with the Pacific Seabird Group Annual Meeting in San Jose, California although the trip was open to anyone. It sold out quickly. We enjoyed a very warm and sunny day! Hardly seemed like winter, especially considering that many parts of the USA are experiencing an "Arctic Freeze." Highlights of the trip included: excellent views of BLACK-FOOTED ALBATROSS; PINK-FOOTED, SOOTY and BLACK-VENTED SHEARWATERS; 2 BROWN BOOBIES; PIGEON GUILLEMOT; COMMON MURRE; SCRIPPS'S MURRELET; RHINOCEROS and CASSIN'S AUKLETS; TUFTED PUFFIN. Marine mammals included: GRAY and HUMPBACK WHALES; LONG-BEAKED COMMON DOLPHIN; HARBOR PORPOISE; SEA OTTER; CALIFORNIA SEA LION; HARBOR SEAL. Quite possibly, the rarest marine animal of the day was one BLUE SHARK. We seldom observe this once common shark these days. The sea surface temperature was a warm 58 F. The fish finder was showing lots of mackerel and rock fish. All images below, copyright, Mark Rauzon. Please do not use without permission.

Kuniko, from Japan, does research with Hiroshi Hasagawa on the endangered Short-tailed Albatross. However, the Black-footed Albatrosses on this trip were the first albatrosses she has ever seen!
Mark Rauzon has been seabirding with Shearwater Journeys for decades, dating back to at least December 20, 1987 when the Pacific Seabird Group held their annual meeting in Monterey.

TWO BROWN BOOBIES
For more than a year now, Brown Boobies have staged a major invasion along the California coast. As many as nine have recently been reported on the Farallon Islands, some carrying nesting material.
