Greetings,
As of this past week, one more hotspot has 100% bar charts. This hotspot (Los Penasquitos Ranch House) has special meaning to us as this is where Beverly and I first started birding together!
Overall we saw a very good completion rate despite the hot weather, with all but the bait barges hotspot being covered in the past week from the main list, as well as a majority of the hotspots from the "gap" list!
Next week we have a smaller slate on the main list, with only 9 hotspots needing 15 weeks or fewer, and this being the last week of the month, we have more days than usual until the next bar chart week starts on April 1.
SDSU Mission Valley River Park is again on the list this week, and needs only 2 weeks. I'd like to highlight this hotspot in particular. Before appearing on the weekly hotspot lists, I had never ventured there. I'm very glad I did and have enjoyed coming back to it. Earlier this year when this hotspot appeared on the weekly list, it yielded the CBA's first Confirmed breeding code for White-throated Swifts! Beverly and I photographed them carrying nesting material into the cracks under the bridge. When I covered it again this Saturday, I again saw Swift Nest Building activity and was even able to record video of swifts hanging to the side of the cracks and then flying out. I also observed very, very active nest building by many Northern Rough-winged Swallows all along the bridge (a first for both CBA blocks the park is in). This hotspot is a relatively unique opportunity to conveniently and closely observe breeding activity for both of these species, as the trolley bridge runs along the entire length of this rather lengthy park, with playgrounds and sports fields situated directly underneath the bridge. The bridge is not elevated very high off the ground, making for very good views!
