01 May 2007, Cetaceanlab reports

Well if this first day of May is any indication of what lies ahead, then this will be a fabulous season. It started for us in the dark, close to midnight, a few faint A5 Resident Orca calls on the hydrophone station in Whale Channel. The calls continued for 45 minutes fairly faint. Just as the tide changed to a flood the calls faded and we assumed the whales must have turned and taken advantage of the free ride the flow the water now provided. The next morning at 9am we could hear very faint calls once again in Whale Channel. The calls were getting closer and closer and soon we could determine that we were listening to A5 and A1 calls. At the same time we received an email from Coast Guard and they reported 18 orcas near the top end of Grenville Channel the day before. They were able to take some pictures which we would take a look at later. For now we focused on the acoustic information as this group of whales moved south in Whale Channel, hoping we would soon hear calls on the Home Station. So far lots of A5 calls, then a series of N47-A1 calls, we were so excited as this would mean the A30s were in this group!! Then silence, not a single call, Hermann went to the point to look, I stayed inside hoping to hear even a resting call. Oddly enough after 15 minutes that is exactly what I did hear, one resting call, then an explosion of calls, all on the Home Station. Next Hermann called on the hand held that I should truly run out to the point. This I did and just in time. Out front there were blows and dorsal fins spread out from us to the little island across the way. We counted at least 15 orcas, vocally we knew we had an A5 group, the A30s and possibly an A4 group as there were definitely a few A4 N4 type calls. Some of the calls were so close, others distant with a beautiful tin like echo that seems to vibrate with the exact rhythm of the water. To our amazement, at the same time as this orca parade, the plumpest male sea lion we have ever seen swam by just a few feet from shore. With out a doubt this male could hear both the calls from these orcas and the blows but showed no interest what so ever. How interesting that they know the difference from a resident to a transient orca so precisely, though for survival purposes this does make sense. This group of orcas continued towards Fawcett, vocal the entire way, then a sudden turn and south they all went. We came back inside to take good look at the pictures sent to us by Coast Guard and sure enough they had the same group yesterday close to Rupert that we were seeing today, the A30s, A42s, A51s plus an A4 group.

Distant calls audible.

Around 7:43am we began to hear the A30s in the distance in Johnstone Strait. The Alaska ferry was coming west through the Strait at the same time. It has since cleared into Blackfish Sound after coming through Blackney. The whales are still calling.

There are now distant A1 calls in Johnstone Strait along with a lot of boat noise. The A30s may have used Weynton Pass to re-enter the Strait.

It sounds like the A30s have returned to Johnstone Strait with the I31s. They are presently getting close to Robson Bight & are calling frequently. Boat noise is persistent in the background of an otherwise lovely recording.
Helena

In addition to the I31s and the A30s in Johnstone Strait early this morning, there was also a vocal humpback (maybe even two) somewhere between Cracroft Point and Robson Bight.

The A36s, followed by the other A1s, headed north through Blackney Pass just before & just after daylight, and are presently in Blackfish Sound. We're listening to their lovely calls without boat noise, and are sorry not to be able to share them with you, as our connection is still down.

We have re-established our connection. let us know how it sounds. The A30s were in Johnstone Strait earlier today. They were ever so briefly vocal around 10am and sounded as if they were not too far off Robson Bight. There are also dolphins around, first in Blackfish Sound last night and then into Johnstone Strait. The heavy rain & southeast winds are over. it is now blowing hard from the northwest.
Helena
15 Nov 2006 15:40:48 PST

Hey it is an A1 day! The A30s,A12s and the A36s (vocal at the moment) have travelled south through Blackney Pass on their way to Johnstone Strait. They look like they might be excited by the prospect! We are.

Unfortunately, we lost our connection again earlier this evening, while we were enjoying listening to all the A1 matrilines being together. This time, the problem is beyond our control, but we're hoping to be "up" again tomorrow. Please excuse the inconvenience.

We've been listening to occasional A1 calls in western Johnstone Strait since late this afternoon, probably from the A30s. They've been silent for the past hour, so we're not sure where they are at the moment. We are waiting.

Hmmm... The last comment needs revision. The A30s are still west of Robson Bight perhaps closer to Cracroft Point. The tide will ebb at 9:18 am PST and this may be influencing their direction.

We just heard from the MacKays that there are about a dozen whales in Beaver Cove foraging. So this means that besides the A30s, who were east of Beaver Cove until recently, there are other groups in the Strait as well. Exciting!
Helena
11 Nov 2006 10:59:21 PST

Distant calls audible.

We started to record at 4:15pm soon after the first clear A30 call in Johnstone Strait. The A30s are now on both the Critical Point and Cracroft systems, perhaps heading east. We also had another two reports about other orcas. At noon, a group was seen heading west past Ledge Point near Port McNeill. Also, a lone male was seen at the top end of Blackfish Sound just before noon. Tempting to think that these whales were transients.

Tracking a single group is probably harder than doing 10 because of the long gaps between bursts. Keeps us on our toes but also scratching our heads from time to time. The A30s are still being heard on Critical Point and CP. They may be east of CP now but they seemed very spread out with independent calls on both these stations.

The boat noise has gone & we've resumed listening to the A30s & possibly other A1s in Johnstone Strait off the entrance to Blackney Pass. The calls sound loudest on the Parson Island hydrophone, but are also on the Cracroft Point & Critical Point hydrophones.

Around 8pm last night the A30s turned up in Blackfish Sound and travelled south through Blackney Pass to Johnstone Strait. Once through the Pass they met up with the A12s who may have returned to the Strait via Weynton Pass. It was an energetic meeting. But as if an echo of October 28th both groups just vanished off our radar. Finally, just before 3am we heard A1 calls once again in the Strait. The calls didn't last long and it has been quiet since. Stormy day today.
Helena

Of course, as soon as we posted the no calls sign, the whales turned up off of Robson Bight. Both the A12s and the A30s are likely westbound in Johnstone Strait. There is also loud boat noise.
Helena

The A12s and the A30s came west to the entrance of Blackney Pass. Two hours before the slack to ebb tide they began their entrance into the Pass & into view. With the A12s in the lead the whales have slowly made their way towards Blackfish Sound. The A30s are now opposite the Lab mid channel while the A12s are most likely already in Blackfish Sound. Good calls from both groups. Very sorry we are still unable to broadcast sound.

Superb sounds!!

The A12s (A33 in the lead) and the A30s just passed through Blackney Pass again. They are now in Blackfish Sound heading west. Again they were very relaxed in the absence of any boats. The "kids" were particularly energetic doing breaches and roll overs several times. A39 seemed to pace himself at the back of the main grouping. A38 was not too far away from A55.
Helena

Distant calls audible.

The A12s and the A30s have contiued to call throughout the day while in Blackfish Sound. All of their calls have been very distant leading us to suppose they "hung" out at the western end of Blackfish Sound. The calls are just now a bit stronger and the tide is coming this direction now although there is very little associated current with this high tide. Maybe it will be enought to encourage the whales back this way. Heavy rain & moderate wind today.
Helena
28 Oct 2006 16:31:28 PDT

Orcas near mics.

Well they did it. The A12s and the A30s are travelling through Blackney Pass. A12 and A33 were way in front. The"kids" & young mums from both groups were bunched together, still very playful. There were lots of spyhops but no breaches this time. A55 was was with A34 while A39 and A38 foraged. The progress south is quite slow with lots of stops & turns but they are more than half way through.
Helena
28 Oct 2006 17:40:53 PDT

Its been weird and wonderful off of Cracroft Point but the whales now seem like they are settling down to a rest. A tug just entered the Strait and it is now quite noisy.

An added note: We have had good news from the DFO. Earlier we thought G23 (G17s) was missing. She is a relatively young mother and her loss would have been very sad and unexpected. Happily, it seems she is fine and still with her group. Meanwhile: The A12s and A30s are now continuing eastward toward the Reserve. We still do not know what happened to the A36s and the Gs after we lost track of them when they headed east a few days ago.

Just so you know: the A12s (we think all of them were there) and the A30s passed back through Blackney Pass from Johnstone Strait to Blackfish Sound this morning on the slack tide. They were through Blackney by 9:25am. Both groups looked very relaxed. There were several breaches, some foraging, lots of tail slaps from the kids, and everyone was rolling around as well. They stayed in Blackfish Sound for a while until presumably they caught the ebb tide and moved on.

Just before dark and just before the slack tide,the A30s and the A12s, came into Blackney Pass and headed into Blackfish Sound where they are now. They were still very relaxed and "opened up" vocally while in the Pass.

Currently we are listening to the A30s and possibly the A12s as well. Earlier today the A30s left the Strait (around 2:30am) and then returned to the Strait with the A12s,A36s and G clan groups possibly via Weynton Pass. We were experiencing a power outage around the time the whales arrived in the Strait and so can't be sure which route they actually took. Regardless, they continued east past CP and Robson Bight. The A12s and the A30s hung back for a while and the A30s came back to the entrance of Blackney Pass. Since then, and quite recently, the A12s resurfaced. Both groups continue to be vocal in Johnstone Strait.
Helena

Just a very short while ago we had a largish group of whales silently travel Blackney Pass to Johnstone Strait. We suspect that this was likely the A30s and maybe even the A12s heard earlier heading west in Johnstone Strait. Possibly these whales circled Hanson Island via Weynton & Blackney Passes. Horrible boat noise at the moment as yet another tug travels south through the Pass.
