Bald eagles

Profiling the beach



Michele Johnson brought together a team of eight Beach Watchers and one fluffy little dog named Chaco to monitor Freeland Town Park on May 18th. Team members were delighted to find two mature bald eagles perched on pilings along the pier as they arrived at the site. This beach has a quite a lot of barnacle coated cobble higher up along the profile line, then areas of hard clay and large boulders in the middle intertidal, and soft mud in the lower intertidal zone leading to an interesting mix of organisms. Among the day's finds were flatworms, woody chitons (Mopalia lignosa), barnacle eating nudibranchs (Onchidoris bilamellata), ghost shrimp, hermit crabs, and six species of clams with bivalve sampling digs bringing up many non-native purple varnish clams (Nuttallia obscurata).

Hermit crab

Nucella lamellosa

Mussel with drill hole

Frilled dogwinkles (Nucella lamellosa) were abundant and several empty mussel shells had drill marks, evidence that they had become victims of that predatory snail species. It was unusual this year that no moon snails or moon snail egg cases were found. A polychaete nearly a foot long came up when a team member dug into the soft muddy substrate at the -1 foot level. The worm was identified as belonging to the family Nephtyidae and was quite an impressive critter!

Cama Beach State Park

For 2010 the Camano BW gathered data to produce the charts shown at the bottom of this website page. Take a look at what collected data says about our species on our shorelines. Then enjoy the pictures below from this year's monitoring.

Double Bluff/Wahl Farm

Looking for organisms

Bull kelp

Anthopleura artemisia

Iridescent seaweed


Double Bluff /Wahl Farm is one of the richest and most diverse beaches on Whidbey Island's annual monitoring schedule. Team captain Kathy Fritts gathered a team of seven to conduct its yearly examination on May 17th . With the tide falling to -2.7 feet, the team was rewarded with some fascinating organisms including 5 species of anemones, 5 species of barnacles, and 3 species of sea stars. Quite a variety of kelps and other seaweeds were also documented including bull kelp, iridescent seaweed (Mazzaella splendens), Sargassum muticum (wireweed), and Ralfsia (sea fungus).

Cucumaria miniata

Rough piddock

Opalescent nudibranch

Tanker

When asked about highlights, team members picked the opalescent nudibranchs, red sea cucumbers, brittle stars, and numerous rough piddocks that were bored into the hard clay substrate. Massive tankers and container ships passed by as the team worked and a young bald eagle watched from the top of a tree snag on a nearby bluff. What a fun day!

Bivalve dig

Maxwelton team profiling



Team captain Tillie Scruton assembled a team of six to look at the Maxwelton Tidepools on May 16th . Whoever Tillie put in charge of weather did a great job as it was a beautiful day. This beach has a short stretch of cobble followed by a substrate composed mostly of sand along the profile line. A massive erratic is set in the sand about 200 feet from the start point and it is loaded with life. This year its inhabitants included red sea cucumbers (Cucumaria mineata), sabellid tubeworms, and surprisingly, northern horsemussels (Modiolus modiolus), a species rarely encountered on Whidbey Island. Another unusual find on the big rock was that of a large California mussel. Several kelp crabs (Pugettia productus) had taken refuge along the base of the erratic and it also served as an attachment point for a dozen strands of bull kelp.

Finn Gatewood led a team of nine at Pratt's Bluff on May 16th. After a long hike down the beach under beautiful blue skies the team went to work finding flatworms, barnacle eating nudibranchs with egg masses, and a large white plumed anemone (Metridium sp.). In addition to the intertidal invertebrates, they also spotted three great blue herons, a bald eagle, two harbor seals that had hauled out nearby for an afternoon of sunning, and paintbrush blooming along the bluff.

Ala Spit

Haliplanella lineata

Eelgrass

Lugworm fecal spiral



Sammye Kempbell's Ala Spit team hit the beach on May 14th when the tide fell back to -2.3 feet. Half of the team was made up of brand new Beach Watchers from the class of 2010 working on their very first monitoring project. They were eager to learn and bursting with enthusiasm. Highlights for the day included digging up a lugworm after finding a hole in the sand marked with the characteristic "cake decorator" fecal spiral, the discovery of a crescent gunnel that had taken refuge under an empty clam shell, and a mottled sea star (Evasterias troschelli) with only three full rays and 2 buds that marked the emergence of replacements for the two that were missing. A polychaete from the family Glyceridae entertained the team everting its massive proboscis and one of the new folks surprised even herself with the utterance that "Worms are fun!" The tiny anemone Haliplanella lineata was also found as were pickleweed and the native eelgrass, Zostera marina. A Skagit County Beach Watcher came by and said hello as he hiked along the spit working on his COAST bird survey. It was a fun day of sunshine and discovery!

Evasterias troschelii

Onchidoris with eggs

Strongylocentrotus droebachiensis


The tide level fell to -2 feet on May 1st as a small but dedicated veteran team checked out Crescent Harbor. Three Beach Watchers took part and one high school student was recruited to help as he hiked along the beach near the start point. More than 50 species were identified including opalescent, barnacle eating (Onchidoris bilamellata), and shaggy mouse nudibranchs, mottled sea stars (Evasterias troschelli), and green sea urchins (Strongylocentrotus droebachiensis). The high school student quickly caught on to the profiling procedure and appeared surprised by the diversity of the beach. A bald eagle kept a stern eye on the proceedings while perched in a tree on a nearby bluff while two Canada geese and a great blue heron did flybys.
