Thanks for doing this, Lance!
For Canoga Park SE, I'd add the Caballero Creek Trail, as well as the "dirt
Mulholland" hiking road which runs east-west up near the crest (park at the
western end of Mulholland).
For Pt. Dume CE, there's the nice sycamore-oak riparian zone along
Escondido Rd., reached via Maguire Dr. off Latigo. It's a mix of houses and
habitat, but it should be hoppin now.
I also see that Calabasas NE is a zero - that includes a lot of Chatsworth
Nature Preserve (incl. Chatsworth Res., which is closed to the public but
bird-able from the perimeter in a few places), as well as the surrounding
hills that include Chatsworth Oaks Park and Woolsey Canyon Rd.
These places are likely <1hr away from a lot of folks reading this.
Not sure what others are seeing, but I'm still seeing "early season"
activity, like House Wrens and Hooded Orioles entering nest sites, rather
than trailing fledglings around. Things should be good for many more weeks
even along the coastal slope, and I always think June is probably the best
time to confirm breeding for a lot of these, since the juveniles will be
loud and often still right near nest sites. So, don't lose hope if you're
seeing a lot right now but confirming very little.
Good birding!
