Sample OBRC report - KIWA


Filler while I'm in BC - a sample of what my OBRC reports look like when I have a bunch of photos of the bird...


===========================================

OBRC Report – Kirtland’s Warbler

1 – def. alternate (?) female

West Beach of Point Pelee National Park

May 18, 2013 – Mid/late morning (right around 10am)

Optics:

            BH –    Vortex Razor 8x42 Binoculars
                        Canon Powershot SX30 camera
                        Canon 1DMark4 DSLR + the 600mm F4 lens

            EH -     Vortex DLS 8x42 Binoculars
                        Canon Powershot SX40 camera


Circumstances – My father and I were birding at Point Pelee along the centennial bike path – walking from the Visitors Centre parking lot and heading north. As we passed the group campground, the trail cuts west across the main road and to the west beach. It then proceeds north again along the scrubby edge that runs the entire length of the west side of the park. It was here, perhaps 10m north from where we first hit the edge – that we had an unknown warbler fly from the side of the path and into a nearby dense area. While I barely registered it as a bird, my Dad thought it looked interesting. We spent a few minutes trying to get a look – however a large amount of plantlife was blocking our view. Eventually I managed to get the bird in focus though a bit of a tangle and had a clear look at a large warbler, pumping its tail! The upperside was generally blue with dark streaking mixed in. The underside was yellow with a fine edge of black streaks. Kirtland’s!

We soon had much better looks as the bird moved back towards the path. We had clear enough views to make the call of the bird being an adult female. Both my father and I were carrying out canon powershot cameras and we tried to get some record photos. She continued to move closer and closer, eventually dropping right down onto the path in clear view – no more than 10 feet away!

Over the next 10-15 minutes, we followed her along the path edge as she foraged and gradually moved northwards. Eventually her track moved away from the path, deeper into the woods and we lost track of her where-abouts. She had moved at least 100m from our initial viewpoint, and I expected that she may continue this motion along this edge of habitat and be difficult to re-locate. It was surprising to me that she was eventually refound – maybe 25 minutes later – by Karl Konze; exactly where we had first spotted her! She then spent the rest of the day – last seen by us near dusk – in a rather small area where the bike path first arrived at the west beach edge – as detailed above.

Description: numerous photos taken with my powershot camera at the time of observation (by myself and my father), along with numerous photos taken with my “better” camera gear in the evening do a far better job than what I can describe. The plumage overall appears to be a perfect match for an adult female, thanks to the uniform flight feathers (not brown/contrasting like a 1st alt bird would be) and the light streaking along the edge of the yellow. The lack of dark/black in the lores indicates a female.

Weather – an east wind was blowing, which I suspected might concentrate birds along the west edge; the reason for our birding plans in this area. This pattern had been in evidence for a few days, leading to good concentrations of birds around the middle of the park along the west edge. The sun was out, but variable throughout the day. Below is 18z surface map for CONUS on May 18.




Notes: I managed two sets of photos clearly showing the bird eating ants.  The bird hung around it’s initial location for the rest of the day. We returned to photograph it again in the afternoon light – and we viewed her until the sun was below some very low clouds in the sky rendering photography moot. I do not believe it was seen the next day.
