Rondeau/Blenheim Christmas Bird Count 2018: a terrific day

The Rondeau/Blenheim Christmas Bird Count is now history. And a bit of history was made. Although we didn't quite set a new record for species observed on the day of the count, at 114 species we missed by one. However we added a new species to the overall count: a Baltimore Oriole which had been seen sporadically prior to the count period, but stayed frustratingly absent until yesterday, which is still within the count week, so it is now added to the overall list of 192 species.

My day started out (not so bright and) early by arriving at Rondeau to try for owls in the pre-dawn. Although the wind was calm, suggesting great conditions for calling and hearing them, the residual wave action from brisk northeast winds the day before interfered quite a bit. I only heard two Eastern Screech Owls although there might have been more that heard me.

I met up with my two birding companions for the day, Josh and Jodi, at the Visitor Centre and off we went, driving the west side of the South Point Trail to the south beach. I was fortunate to have both Josh and Jodi with me for their camaraderie as well as their younger and superior eyes and ears

I always spend a bit of time first thing scanning the lake for waterbirds on the move. Sometimes there isn't much movement, but today was an exception. Aside from the usual mix of scaup and mergansers, we had White-winged Scoters and an amazing 18 Red-throated Loons. The loons were not exactly surprising, as up to a 100 had been seen off the east beach in previous weeks. But since there are only a couple of records of this species for the count (two I had seen back in 1981, and another two last year) it was noteworthy indeed.

Combined with those that others saw in their respective territories, our count total of about 70 red-throat individuals was a terrific start to the day.

The walk out along the south beach was certainly one of the best days in the 30+ years I have been doing this area. Some years it is inaccessible due to snow, ice, howling wind and strong wave action battering the fallen trees lining the lakeshore. Today it was amazingly pleasant being sunny with very light winds, and temperatures nicely above freezing. The south beach is a narrow strip of sand that (usually) separates the marsh and lake, at least when the high water levels haven't breached the sand spit causing a brisk and steady flow of water back and forth. There was very little wave action, making trekking along the beach on either the marsh or lake side very easy, which is always important as we cover the approximately 7-8 kilometer hike to Erieau and back.

Small birds were few and far between, although we did get things like Marsh Wren and Swamp Sparrow. One of the goals of this bit of territory is to see the diversity of waterbirds tucked in at the marsh/bay interface. We ended up with 21 species of waterfowl, including the only Northern Shoveler on the count. Other highlights included two Sandhill Cranes, two Belted Kingfishers, four American Coot, a single Great Blue Heron and a single Snow Bunting.

Our return to the start of the beach walk was highlighted by none other than a hatchling Northern Map Turtle, struggling against the waves.

It is possible that some earlier wild wave action dislodged this little fellow from its winter hibernation site buried in the sand somewhere along the beach.

A brief stop at the Visitor Centre at mid-day turned up things like American Goldfinch and White-throated Sparrow.

Our next area to target was the Marsh Trail, and in particular the southern parts. As is sometimes the case, birds were noticeable by their absence, although we did see lots more waterfowl on the open water of the marsh.....
.... and get things like Bald Eagle. We ended up with five eagles for the day.

On the return to the trail entrance, we added a few Red-bellied Woodpeckers and a single Pileated Woodpecker, among other species.

With the main part of our designated territory finished, and being now at the north end of the park, we decided to spend a bit of time searching for things like the White-eyed Vireo and Great Kiskadee. The former had already been seen briefly by others, but the latter species remained absent. Our walk along the southern side of the maintenance yard cedars was initially quiet, and I pointed out where I had seen and photographed the vireo just a few days earlier. And there it was again, in exactly the same spot.

A couple of other birders were nearby looking for it, so we got their attention and the white-eye kept us occupied for several minutes.

After a while, our group dispersed while Josh and I headed to the north side of the maintenance yard where the kiskadee had sometimes been seen in days gone by. A few minutes later we decided to head to the campground where the kiskadee had also been seen from time to time. On the way over, while Josh was facing me in conversation he stopped while looking over my shoulder exclaiming 'there is an owl'. I quickly turned and looked. It was probably only 50 metres away and low in a deciduous tree. It was a large owl, but clearly not a Great Horned. It only took a split second for both of us to conclude it was a Barred Owl! This was totally unexpected, as there are only 4 previous records for the park checklist area, and none since 1981. After getting a few photos, we quickly texted some other birders.
It was late enough in the afternoon that most had already finished their territories, so were able to arrive fairly quickly. The owl was on the move, however, and by the time the ten or so birders showed, it had moved into the campground. And there it was found again, at one point having picked off an Eastern Grey Squirrel which had undoubtedly never had any experience with Barred Owls (and would never have another!).

So although we didn't luck out with the kiskadee, the Barred Owl was certainly a bonus bird even though it was not a new species for this count, having been recorded on one previous occasion.

The Great Kiskadee continues to be absent, not having been seen or heard since December 9. It is interesting to know that one had shown up in recent days in Indiana, so perhaps it has made its move towards a more likely part of its range. Or maybe 'our' kiskadee will reappear somewhere in the Rondeau area, since it has a habit of disappearing for several weeks and then reappearing for a week or two. Time will tell, but for now, I have replaced my header photo of the kiskadee with the latest celebrity, the Barred Owl.
A final note: in addition to the Northern Map Turtle we saw, I heard that others saw Eastern Garter Snakes and Eastern Comma butterflies in at least a couple of different places on this warm and sunny day. Certainly not the kinds of things one expects to find on a Christmas Bird Count, but I guess here in the banana belt, we should expect the unexpected!
