AUG. 16, 2011 - Janet & John Foster are in our area now, after  
shooting some good high-definition video of migrant shorebirds in New  
Brunswick at Mary's Point and then Johnson's Mills in upper Chignecto  
Bay of the Fundy ecosystem.  Apparently at Mary's Point (sw. of  
Moncton) they were there at the perfect time to see about 70,000  
shorebirds, more than they have had there in a long time.  And then  
big numbers of 100,000+ shorebirds at Johnson's Mills (west of  
Sackville) for two days.  Now they want to look for more footage of  
the shorebirds and of their food, mud shrimps etc., here in the Grand  
Pre area.

Today's daytime high tide was at 3:13 p.m. and 12.5 metres of  
amplitude (mediocre).  The Fosters wanted me to show them some  
sandpiper food, especially mud shrimp or Corophium volutator out on  
the mudflats; however, we were too late in starting, so we will try  
that tomorrow.

Thus i gave them a "nickel tour" of some of my favourite local spots  
for the shorebirds from just before to after high tide.  We started  
at Evangeline Beach at the canteen/parking lot area, and we got lucky  
just like Gary Murray did two days ago at the same time and place.   
We found a nice large flock we guessed at 10,000 peeps (but possibly  
twice as many), just below and slightly west of the canteen on the  
rapidly disappearing upper beach as the tide came in.   This flock  
was almost totally semipalmated sandpipers, with just a few white- 
rumped sandpipers among them.  They were quite close to us, and we  
were viewing them by looking downward at a steep angle.  There was  
nobody on the beach to disturb them, but they were very restless with  
Zugunruhe, often taking off noisily as a big flock or as smaller  
groups, then flying off over the water, back and forth, only to  
circle back and land among the same birds or in the same area as they  
left.  This all took a long time, and the upper beach gradually  
disappeared, causing the peeps to all take off and fly back and  
forth, with splitting and rejoining over the water, and eventually  
flying away and out of sight toward the east (the usual pattern  
before high tide.  We also had a sudden appearance of a peregrine  
falcon flying low and from the west, right past the flushed  
sandpipers but not chasing any, and out of sight to the east.

Once all the shorebirds were gone, I showed the Fosters the nice  
signage on the birds and their foods and ecosystem here, along with  
nice maps and photos showing the nesting range in the North and the  
migration arrows to northern South America (Suriname), which is about  
5000 km. away and takes 2-3 days and nights of non-stop flying to  
reach.  This is why each peep doubles its weight during its 7-10 days  
or so of feeding in the Upper Bay of Fundy (here).   The signage is  
at the shorebird viewing platform on the north edge of the canteen  
parking lot.

It was still about 1.5 hours before high tide when we next drove to  
Avonport, where along Bluff Road I showed them Avonport Beach and  
Penny Beach, where good numbers of flying flocks can be seen at high  
tide and later.

John spotted an osprey, which is a very unusual sight in our area of  
The Valley, and it flew right over our car.

And I mentioned that in years past a good spot for roosting  
sandpipers was Blue Beach, just east and south from Horton Bluff.  We  
drove there, parked in the lot near the Fossil Museum, and then  
walked down to the beach, where there were 6-8 fishers for striped  
bass (we saw 3 small non-keepers caught by one fisher during the hour  
we were there).

There at Blue Beach we were delighted to discover another? big  
restless flock of about 10,000 (or many more?) sandpipers that were  
flying a lot and then landing and roosting for short periods on the  
shingle beach on both sides of a narrow wedge of water.  Again these  
were 99% semipalmated sandpipers, as at Evangeline Beach, and I think  
there's a good chance this was the same flock we had watched back there.

Interestingly, John Foster spotted some peeps up high on the hillside  
that slopes down to the beach; these were 21 semipalmated plovers  
with about 4 semipalmated sandpipers.  They had found a very restful  
location, unlikely to be disturbed.

The fishers didn't bother the birds at all, except when one of the  
fishers relocated by walking through the big flock, which flew off  
but then quickly resettled after he walked by.  Later one couple of  
recreating humans arrived with their unleashed two Labrador  
retrievers, which were no problem for the birds.  But probably on  
weekends the birds have a harder time finding places to rest during  
the high-tide period? (since recreators would then be much more  
numerous, with both dogs and restless children?).

I lost track of the times, as we watched those roosting peeps.  At  
one point about 3/4 of them flew off and over the water, and, after  
circling back and forth several times as if undecided (but probably  
just restless?), this big flock flew off to the west and out of sight  
(probably to the east end of Evangeline Beach?).  And the rest  
settled into a long deep rest on the shingle beach until we left  
them, about an hour after high tide.

One more point: at one point while Janet and John were filming, I  
scanned the water of the Minas Basin with binoculars, and I found 2  
sizable flying flocks of small shorebirds or peeps, flying probably  
from the Noel Shore somewhere to the north and toward the west and  
out of sight, perhaps again heading for east Evangeline Beach? (or  
perhaps further west to other mudflats or the mouth of the Cornwallis  
River?).
