J pod and L87 call on Lime Kiln hydrophones

2011/03/06 in Acoustic analysis, Lime Kiln State Park, southern resident

Today J pod (and L87) came in through Baynes Channel and traveled north up Haro Strait (based on Ron Bates report to Center for Whale Research mentioned on Orca Network Facebook page. The whales made some clear calls and clicks on the Lime Kiln hydrophones. Here is a sample recording of the calls which mainly were repeated S2s. Jeanne Hyde first heard a few calls at 10:50, but the following auto-detections only began at 11:28.

  1. What I called S2s in these are kinda long and therefore more like S3s to my ear. Anyone have an opinion on the call IDs?

    Here’s one on-line reference for learning call types…
