Swallows Soon to Migrate South


                                                 Swallows Lining Up On Utility Wires

On August 1,  I was surprised and excited to see swallows lining up on the utility wires in the Scotch Settlement, York County, area.  I haven't seen this behaviour in many years and I was very happy to witness it this year.  There were about 100 birds of 3 species (Cliff Swallows, Tree Swallows, Barn Swallows) cavorting around and vying for what appeared to be preferred positions along the wires.  They were actively flying to and from the wires and going afield only to return quickly.

There was obviously much excitement among the birds.  It did not seem to matter which species lined up closely to which.  They appeared to all be getting ready for something exciting.  At one point an American Bittern flew across the road and a few swallows took after it and either chased or accompanied it across the field and out of their gathering place.  That looked like a squadron of jet fighters escorting an enemy plane out of protected air space.

Late July through September is the preferred time of departure of 'our' swallows.  Cliff Swallows depart after the nestlings fledge which has happened in that area.  Their departure is listed as early August through early September.  Barn Swallows depart from late July onwards with the migration departure peaking from late August to early September.  Tree Swallows depart a bit later with most leaving in September.  Cliff Swallows migrate to southern Brazil and south-central Argentina.  Barn Swallows go mostly to South America as far south as central Chile and northern Argentina.  Tree Swallows migrate to the southern US, Central America and the Caribbean.  Looking at their destinations, you can see why the Cliff and Barn Swallows leave earlier than the Tree Swallows.  They have much farther to go!

Migration is an amazing and interesting phenomenon.  I am thankful these swallows come to New Brunswick to breed, raise their young and enjoy the habitat our ecosystem provides.  Our declining insect populations is a concern.  There is increased mortality in young swallows partly because of shrinking food supplies, the insect population.  We must protect the nesting sites of these birds and encourage them to spend their short summers with us.  We also must follow regulations against pesticides and pollution in order to protect the swallows and other inhabitants of our environment (including ourselves).

Black-necked Stilt Seen in New Brunswick

                                                                   Black-necked Stilt

On Friday, 5 August 2022, an Ontario birder who summers in New Brunswick was checking for shorebirds along the shoreline of the St. John River between the bridges in Hartland, NB.  We are fortunate this woman was familiar with shorebirds and recognized that what she saw through her binoculars was a rare species for New Brunswick, a Black-necked Stilt.  She also knew how to alert others by contacting a local birder who posted it to online discussion groups.  That began a magical day for birding for a handful of New Brunswick birders. 

It is unknown when the bird arrived in Hartland and from where it came.  It undoubtedly is a vagrant which migrated up (or down?) the St. John River.  It is a male adult and is probably dispersing from the breeding area before returning south for the winter.  Just how far are we referring to here?  Well, the Black-necked Stilt (Himantopus mexicanus) normally summers in southern Florida, the coastlines of Georgia and North and South Carolina, the mid-western and western states and southern Alberta and Saskatchewan.  They winter in California, the Gulf coast and southern Florida south to the tropics. So this bird is far from the normal movements of this species.  

And how rare is it in New Brunswick?  We have had 4 recorded occurrences since records have been kept: 1862, 1880, 1982, 2000.  Nova Scotia has had a few records as well.  The 1862 and 1880 records were confirmed because the birds were 'collected' (shot and sent to the museum for mounting).  Unfortunately that is what they did in those days.  The 1982 and 2000 records are listed as 'unconfirmed' which actually means that no specimen was collected and no photos were taken.  But, today we are a photographic generation and there are lots of photos of this visitor, I would guess well over 1000 were taken that day.  All the photos in this blog post were taken by me.

Hartland is a very picturesque place.  We wandered around along the shoreline which was mowed grass in most cases  checking for the bird from both sides of the river.  We crossed the historic covered bridge to move from one side to the other.  The bird was feeding along the shoreline of the river and the island located there.  The shoreline was composed of rounded rocks of various sizes with a bit of sand.  On the east side a brook flows into the river bringing cold water and rich aquatic food. This made good feeding for the Black-necked Stilt and the 2 Lesser Yellowlegs which it was keeping company with some of the time.  Viewing and locating the bird was difficult because we were looking into the sun for a good part of the time.  As bright and beautiful as the bird is, it was well camouflaged with the bright sunlight reflecting off the water and the black of the wet rocks.  The difficulty of seeing this bird was a surprise to me.  Even though it is a rather large shorebird, 33 cm long with very long legs, it still was difficult to see.  One could pick it up only when it was moving or silhouetted against the bright water.

Please see a previous post on this blog for information on the life history of the Black-necked Stilt; 'Black-necked Stilt - Nemesis Bird', June 4, 2022.

This species was my 'nemesis bird', meaning I have been trying to see it for at least 30 years.  I was just never in the right place at the right time while out west or in the south.  I have chased around flocks of American Avocets which it sometimes flocks with but with no success.  I had missed the 2000 bird from Jacquet River by 15 minutes.  But on that special Friday luck was with me.  I had many good looks at the bird and was able to photograph it from a safe distance with no disturbance to the bird at all.  It was fun to share the excitement with the group of NB birders for which it was also a 'life bird'.  For me it was the 351st avian species seen in NB over my lifetime!

What did I notice about this bird?  First, it is a beautiful shorebird.  The black and white plumage pattern is striking.  And probably the most striking feature is those impossibly long legs!  They are bright pink (or sometimes red) and the feet are small.  The literature tells us they are partly webbed enabling the bird to be able to swim although it rarely does.  The black bill is very fine and dagger-like and about 6 to 7 cm long.  The black crown which runs down the back of the neck is offset by the white on the forehead, throat and ventral neck and especially by the white eyebrow patch.  In spite of the long legs, the bird is very agile.  When it flies the legs are extended straight out behind.  It obviously can fly very well given the distance it has come!  In summary, a very striking bird and so exciting to see.

We were able to compare it to the two Lesser Yellowlegs it was hanging out with.  See the photos below.  The Black-necked Stilt looks larger in the photos in comparison because it was closer to the camera.  Note, the Lesser Yellowlegs are 27 cm long compared to the stilt which is 36 cm long.  This measurement is taken from the tip of the bill to the tip of the tail and does not include the long legs.  The stilt's body is actually quite small.

The literature tells us that the Black-necked Stilt is considerably vocal.  Unfortunately we did not here its 'kek, kek, kek'.  It was far enough away that we might have missed it.

Many thanks to the NB birders and to our ON visitor for making it possible for many of us to see and learn about this species.  Unfortunately the bird was seen only that one day.  We hope it won't be another 20-plus years before we see one again.

Local Church Protects Cliff Swallows

                                                               Cliff Swallow Nests on Church


 For some reason the Cliff Swallows (Petrochelidon pyrrhonota) like to build their nests on the Scotch Settlement Church, York County.  And what is even worse for the parishioners is that they much prefer to build them over the main entrance!  Every year that creates a problem for people entering and leaving the building.  This year there are about 12 nests, all built over the entrance.  Some nests are singles, some doubles and some triples.  That makes a lot of activity, birds coming and going to feed hungry chicks.  

The nest-building this year is very robust.  There is a constant chorus of chirps and warbles as adults are coming and going and young are fed or letting it known that they are hungry.  The birds do not seem to be inhibited by the people of the church.

The people of the church, however, do have a problem with the birds, or rather, their droppings.  As the nests became occupied in the spring the problem soon became evident.  Bird droppings began to appear on the carpeted steps to the church and the people had to quickly duck as they entered or left the building. An earlier attempt to dissuade the birds from building in that location, the hanging of CDs in the preferred areas, had failed.  The birds just built right among the CDS, even incorporating some of them into the mud of the nests.  

So, what to do?  The church people used a simple solution.  They turned the top step on its side in order to prevent the buildup of fecal matter on the carpet.  Then they roped off the front steps and asked the church goers to enter and leave by another door!  Bravo to the Scotch Settlement Church for putting the well-being of the birds ahead of their convenience!  After all, the birds are God's creatures too.  See below for how they altered their front door.

 The bird enthusiasts and environmentalists in the area are happy.  Many thanks to the people of the Scotch Settlement Church for putting their concerns for the birds into action.  They have set a good example of care for the environment and its creatures.
