4-6/7-13 Nighttime Sounds Lead to Daytime Whales

Saturday/Sunday, April 6/7th
...Saturday was a sunny day...a flock of geese heading north...


...there was a Transient 'party' up in the Strait of Georgia on Saturday...I wasn't present, but heard about it...
...some of the whales came down through Active Pass and continued on, coming in range of the Orca Sound hydrophones at about 8:30pm...about 20 minutes later they could be heard on the Lime Kiln hydrophones and that lasted until about midnight...it's common for Ts to be very vocal when they have a 'party' going on...
...here's just a few of the many different sounds from the party...

...Sunday morning I get a call from a friend "Look out your window."  (Is that cool or what?)
...a bit rainy, and it took a while but finally I saw a dorsal fin just as it was disappearing...quick grab camera and run up the road as fast as I can...they were far off shore...luckily I was able to get a few pictures...
...oh, look at the 'wow' in his fin...I think it is T49C...
...that's Mr. Floppy Fin - T19B...so I knew the T18s were present...

...I watched them for a while...they were taking long dives...and then a dive so long I couldn't find them again...I went back home...about 45 minutes later I decided to go look again - the rain had stopped and the seas were flat calm, just maybe I would see their blows...
...I went to County Park for a better vantage point and was I ever lucky - there they were!...they were in mid-channel still moving along at a steady pace...

...out on Maya's Westside Charters and while on our way we passed some Brant geese...a link for more information about these interesting birds...

...we caught up to the whales and a few others who were watching them...they had gone around the backside of Morseby Island and were just coming into Swanson Channel when we arrived...
...and yes, T49C was present...he's on the left and T19B on the right...
...T19B and his leaning dorsal fin...
...they were heading up Swanson Channel now...three of the group of five...

...before this group of 5 headed up the channel and while they were moving in circles, someone spotted a blow on the other side of the channel...it ended up being T20 and T21...here's a picture of them after they had moved across to the Morseby Island side (read below for the details)
...what was most interesting to me is that when we first arrived on scene the T18s and T49C were moving slowly in circles...but they didn't appear to be hunting...later I wondered if T20 and T21 had something to do with the behavior of the T18s...
details:
...T20 and T21 are commonly seen traveling by themselves, even when other transients are around.
...today, T20 and T21 were spotted over on the Pender Island side of Swanson Channel heading up the Channel at the the same time that the T18s and T49C were on the Morseby Island side of the Channel - at first moving in circles and then heading out into the middle of the Channel and heading up...
...T20 and T21 were next seen way up ahead and on the Morseby Island side of the Channel, meaning they had crossed in front of and across 'the path' of the T18s.

...was the group of 5 waiting while T20 and T21 crossed over - did the T18s have a 'yield sign'?...not sure what if any meaning there is to it all...
...we know that the Residents and the Transients give each other a wide birth, but are there also some Ts who give each other a wide birth?
...I find that very intriguing...
