Nesting Season Slowing Down

The torrential rains on the south end of Wrightsville Beach have finalized the nesting of the Black Skimmers and the Common Terns that were nesting on the front of the dunes the last week of July.  On the last nest check (7/30) we had 12 active nests on the front dune and on the beach, but the storms and the heavy rainfall in the following days that week washed all the eggs out of the nests. 

THE GOOD NEWS 
We have one strong and fast growing Black Skimmer chick to enjoy! And flying lessons have already begun for this little one.  
  
Here is our Black Skimmer chick practicing FLIGHT!! Notice it is only about 2 feet above the ground! A milestone.... If you zoom in, you can see its leg bands!

On August 7 the chick was caught and bands were placed on its legs.  You will notice a metal band on its right leg and a black “field readable” band with white numbers…#47 on its left leg.  With this field readable band we have the possibility of easily seeing this chick when it returns to Wrightsville Beach in future years and knowing it was our 2018 special chick!!!  


















We continue to see large groups of our Black Skimmers on the beach and in the inlet! There were 191 Black Skimmers in the colony the other day.  The birds are moving all the time now and if you happen to arrive when they decided to fly across the inlet and roost on the other side it seems like the season is over but it is not.  Large numbers are on the move because they do not have chicks to care for in the posted area.

Black Skimmers and Common Terns will randomly fly over the posted area and some Least Terns  and Royal Terns can occasionally be seen.

While our NC Audubon biologist Lindsay Addison was on the beach last week she noticed that four Black Skimmers cooling by the water had metal leg bands.  She was able to use her scope to read the silver engraved numbers, recorded the numbers and looked up the specific band numbers on the national bird band database.  GOOD NEWS: The Skimmers were banded as chicks at our south end nesting colony on Wrightsville Beach in 2013, 2014 and 2015!!!  They are our birds and have returned to our beach to nest!!! 
We currently have approximately 160 nesting pairs = at least 320 Black Skimmers at the South End.

Oystercatcher Chick Update


We have not seen the American Oystercatcher chick on the beach or being fed by parents for over 48 hours. The parents have been seen on the beach alone and we are uncertain about what happened to the chick. According to the American Oystercatcher Working Group, most chick mortality takes place in the first two weeks of life and generally just prior to fledging (flying). The most frequent causes of death for chicks in North Carolina include exposure, mammalian and avian predation, ghost crabs and human disturbance.

We are pleased to have been able to share our first chick in three years with many beach goers and we're disappointed in this result. 


But we remain optimistic about this challenging nesting season and look forward to Black Skimmer and Common Tern chicks soon.

One of our WB Bird Stewards, Bonnie-Jeanne Berg, not only expressed what many of us are feeling but took some (now cherished) photos of the chick.

" I referred the chick to my Saturday morning beach-goers as our "Golden Child".... and what a show we had from the family... hope you enjoy .... and I am looking forward to our next babies... the show must go on.... and how thankful we will be!"


look closely to see the chick's legs under the mom

American Oystercatcher Chick



photo by Tom Hanna

This little chick is the first American Oystercatcher chick seen on South Wrightsville Beach since 2015!! 

The young chick was able to stand upright and run short distances within hours of hatching. Chicks will escape predators by hiding, particularly in the first 10 days.  A chick responds to parent alarm calls by running for cover, then lying immobile. 





















The oystercatcher banded with CKX is the female, the momma of our chick!



Within 1–2 days of hatching, we watched the parent and chick head towards the water.
On the way to the beach!

Our chick is fed bivalves, mollusks, crustaceans, worms and other marine invertebrates that inhabit intertidal areas. Chicks are dependent on adults for food for at least 60 days after hatching.

And in other news.....

We recently discovered Black Skimmer and Common Tern nests (with eggs) on the beach outside of our posted area. So the postings have been moved and there is a lot of activity to watch on the beach!

Posting being moved so that nests are protected.
Activity within in the newly posted area.

























The Wrightsville Beach Black Skimmer colony appears to be the largest in the state of North Carolina this year! Upwards of 200 can regularly be seen at the water's edge or flying overhead.

and finally.... here is a short video of the new chick for you to enjoy!

Today's Lesson: Nest Check vs Nest Census


Black Skimmer nest with 2 eggs!!

We have news to brighten your day!  Our NC Audubon biologist, Lindsay Addison, conducted a NEST CENSUS early this morning.
First thing you need to know is the difference between a “nest check” and a “nest census". Lindsay has been doing "nest checks" regularly since the beginning of the season.
NEST CHECK
A nest check is a sampling of nests marked with tongue depressors at the beginning of nesting to enable the biologist to follow up on the activity of that particular nest.  A number is assigned to the nest, such as BS 02 which marks a Black Skimmer nest #2, CT for Common Tern, etc.   These labeled nests are checked on a regular basis to follow laying of eggs, loss of eggs, and anticipation of hatching.  It also enables us to determine eggs that are abandoned (nonviable) and predated by gulls or crows because they were obviously pecked.  Lindsay has been following between 16-30 nest.

As you know, we have lost many nests to crows and gulls, but the Black Skimmers, Common Terns and American Oystercatchers have kept re-nesting!

NEST CENSUS
         A nest census is conducted when the biologist feels that we are at the peak of nesting…which Lindsay did this morning at 6:30 AM.  Early morning is always the best time to conduct a census as the birds have rested during the night and the temperature is the coolest it will be during daylight.       
          A nest census counts EVERY nest in the colony.

And the number of nests is (drumroll, please) ….
     BLACK SKIMMERS       137
     COMMON TERNS              7
     AMERICAN OYSTERCATCHERS   2

Lindsay reported that we had not lost any Black Skimmer nests since her last nest check and that the Black Skimmer nests have between 1-2 eggs.  There do not appear to be any nests with 3-4 egg clutches.  Approximately 25 Black Skimmer eggs were abandoned and another 25 or so were predated by gulls or crows.
The 3 Common Tern nests are still there from her last check and we have 4 new nests for a total of 7!!
The American Oystercatchers still have the two nests since her last nest check.
We are so happy to share this good news!  Our Black Skimmer colony appears to be the largest in the State of North Carolina this year.  
We anxiously await the arrival of some chicks!
Enjoy your weekend and we hope to see you on the beach!

Happy Summer Solstice!


LATEST NEWS FROM LINDSAY’S NEST CHECK

AMERICAN OYSTERCATCHERS 

Although we lost the four nests we were following on the south end, as of Lindsay’s last nest check we have 2 active nests on SWB.  We have a number of oystercatchers visiting the colony now resulting in territorial displays by the lone oystercatcher on the beach whose mate is on the nest.  At times, oystercatchers who have lost nests at Masonboro Island, for example, and have given up trying to re-nest will visit Wrightsville Beach and disturb the nesting birds here.  The piping is loud and the head bobbing displays are rather comical and fun to watch.

Little CP2 in the summer of '15
photo by Michelle Frazier
Some really wonderful Oystercatcher news….A lot of effort goes into banding American Oystercatchers in North Carolina with green “field readable” bands so we can follow the specific activities of a particular bird.  Yesterday Lindsay was able to recapture an Oystercatcher with the green band of CP2 on Lea-Hutaff Island.  CP2 and her mate are re-nesting with a one-egg clutch.  CP2 is a female (DNA from her feathers determined that she is a female) fledged from the south end of Wrightsville Beach in 2015…the last year we fledged chicks on Wrightsville Beach!!!  How fantastic is that!!! One of “our” chicks is now nesting in our area….!!!!   Lindsay’s dedication and hard work to capture and to band Oystercatchers in our area enables us to celebrate this wonderful event!

BLACK SKIMMERS 

The nesting Black Skimmers did better this last nest check and only lost 3 nests of the 16 specific nests that Lindsay is monitoring due to predation.   

Large groups of Black Skimmers continue to gather at the water’s edge to cool themselves and switch places with their mates on nests in the dunes.  There were over 250 by the water on Tuesday this week, and 232 yesterday.   The Wrightsville Beach Bird Stewards love sitting with the Skimmers at the water’s edge and chatting with people about these beautiful birds as they walk by.  Our beach visitors love hearing how the Black Skimmers migrate from South America to nest here with us!


Impatience!

COMMON TERNS 

We have 3 active nests as of our last check.  Avian predators (likely crows) have hit them hard.

WILLETS 

It is likely that the Willets have taken their chicks towards the Coast Guard Station and Banks Channel.  We have not had any reports of chicks on the beach or caught in the inlet current this year.  Nor have we seen any aggressively protecting behavior of the Willets recently which leads us to believe that they have moved their chicks.

Hope Continues For Our Struggling Colony


Challenges to a successful nesting colony on the South End of Wrightsville Beach continue, but our Black Skimmers and Common Terns continue to make scrapes, lay eggs and are not giving up!  We remain hopeful!

The Black Skimmers seem to enjoy posing for pictures...

Lindsay Addison, Coastal Biologist for Audubon NC, conducted a nest check very early Tuesday morning (6/5) and here are the latest results…


The Common Terns continue to lose nests to avian predation (probably crows) but we now have 4 active Common Tern nests.  We have between 5 to 7 pairs of Common Terns at the colony.  Our most visible Common Tern nest is on the top of the dune right in the middle of the sandy opening at the inlet as you look into the posting from the string. 

 We expect chicks very soon from the first nest recorded.  This particular nest is on the sandy vegetated dune on the left among the Black Skimmer nesting area -- looking into the posting from that same spot!

Our three American Oystercatcher nests that were right around hatching appear to have failed….but Lindsay found one new nest! We have seen 5-6 Oystercatchers hanging out on the beach by the inlet.

The 12 Black Skimmer nests that Lindsay marked last week to monitor productivity have had severe damage…Likely from disturbance.   The skimmers lost half the nests that were marked on her nest check last week which is an unusually high percentage.  Lindsay counted seven predated eggs, all probably crows because they have holes pecked in them, and 11 abandoned eggs from 9 or 10 nests.  Some of the marked nests are just empty with no eggs in sight.

THE GOOD NEWS!  The Black Skimmers are not giving up as we now have approximately 30 active nests and the Black Skimmers are still scraping and laying eggs.   Six pairs of Black Skimmers have appeared on Masonboro Island this week… likely from the south end.














On Monday morning, 6/4, Willet chicks were seen strolling along the beach with a parent.

A special thanks to the fifth grade classes at Wrightsville Beach Elementary School for designing the pictures on our postings!  They enjoyed coming to the beach to see how their signs help protect the colony.  Our shore birds gave them a warm welcome!
