It is at the storm drain on Sullivan's creek near the southern edge of Yowani golf course. Mind you I had less than a minute to take the photo and they were gone. Today the welcome swallows were there, some crested pigeons, and lots of starlings having a bath. Most of my recent sightings have been along that southern edge of the golf course. It's not the most attractive location but I just go there as it's close to home and enjoy seeing what I can find.
Nice! That spot that you mentioned is a great quiet spot for birding, so cherish it! Used to head down there, nearly every day after school and it is quite amazing the species you get. Keep up the sightings!
