Here in Nakusp Spring continues and with it the mystery of
migration.
The first flourish was weeks ago when, while snow and ice
still covering the ground the first optimistic Robins flew in. They were the
first guard only as since then hundreds upon hundreds have joined them and
moved through this area. Back in 2009 American Robins were clearly one of the
more common and widespread species as it was perhaps the only bird recorded
daily throughout our three week visit however that experience could not prepare
one for the numbers that are actually here. In spring the fields are full of
them; again and again you see Robins; in the yards, by the roadsides. Counting
Robins would be a full time job and then some.
And then more Robins come. And then more.
And they’re still here.

As the juncos arrived other flocks amassed to leave.
Redpoll, their hundreds disguising the solo hoary spy within, again crowded the
roadsides before finally leaving for fertile fields north. Pine Siskins, too,
have either spread north or west or east into the forests to breed, abandoning
their winter flocks for the relative solitude of mate and nest.

Yellow-rumped Warblers in small but ever increasing numbers
joined the Bluebirds and pretended to be flycatchers along the fences; trying
desperately to convince all that a warbler is a species of the open. The
warblers are stunning generally and the yellow rumped particularly so and it’s
not a surprise that other warblers take their time to arrive and so do not have
to compete with the yellow rumps and their splendor. By the way there are two
main kinds – subspecies - of the yellow rumpeds; Audubon warblers – once a
specie in its own right – is the common one and has yellow not only colouring
his [or her] rump but his throat and crown as well and the second, the Myrtle,
he of the white throat and rare; preferring lands to the east of the Rocky
Mountains.

Sparrows have come too. Over winter the resident Song
Sparrows survived in the occasional company of the few and the lost; White
throated, White crowned and American Tree. The last three have left but the
Songs have stayed their breeding song sounding early – even before the arrival
of the first Robins.
Savannah Sparrows and Lincoln Sparrows have now entered our valley albeit in small numbers until this week when a new flock rolled into town; White crowned Sparrows. They are every where, attracting the attention of cats, accipiters and birders alike.

The only slightly downside to all this is that I am trapped in classrooms during the day and I know what is happening outside. My friend Gary Davidson, who is retired, acts like my scout and, at the risk of frustrating me, each day adds new species to my frontier. Yesterday he added his first Orange crowned and Nashville Warblers, a Chipping Sparrow and in news that may even excite my children, his first-of-the-year Rufous Hummingbird.
