Bay Area Weekend: desperately seeking number 1500


A couple of weeks ago I was starting to pack for a weekend away in Rhode Island when Vladimir Dinets posted that Northern Right Whale Dolphins were back – in big numbers – in Monterey Bay. This was very exciting.  Not only were Northern Right Whale Dolphins one of my 21 most wanted species in the world …. I just have a thing for them, OK… but my mammal life list was at 1499 and I wanted my 1500th tick to be something more charismatic than a rodent.

I spent Thursday night wondering how good my chances of finding the dolphins were: they had been seen at the start of the week, but not since.  But by Friday lunchtime I could no longer resist.  I abandoned Rhode Island, found an award ticket to San Francisco and was on my way to the airport 4 hours later.

Mid April through mid May is a great time to see Killer Whales in Monterey, when Bigg’s (Transient) Killer Whales often come to the bay to hunt migrating Grey Whale calves. Monterey Bay Whale Watch run all days trips during these weekends which are specifically aimed at spending time with the Orcas. The extra time at sea also, of course, increases the chances of seeing a range of marine mammals.

Nancy Black, Monterey Bay Whale Watch’s founder, was at the wheel and as always we passed heaps of California Sealions as we left the harbour,

interspersed with occasional Sea Otters.

It wasn’t long before we found our first Humpbacks (we must have gone on to see 50 that day).  But while we were stopped to look at them I spotted a large pod of distant Dolphins, which Nancy was happy to chase.


Mega Pod

The pod was huge and stretched well over half a mile: Nancy later estimated it might have comprised up to 4000 animals.  Although most were Pacific White-sided Dolphins, I was pretty sure I saw a few Northern Right-Whale Dolphins further back, though it took longer to get good views of them.

Both species were extremely photogenic and active. And although there were a few Right-Whale Dolphins towards the front of the pod, we had must better views of many more animals later on when we found the back of the pod.

I couldn’t complain about my sighting of my 1500th mammal (even if that number 1500 is a bit of a fluid milestone, given the likelihood in future of splits, lumps and mistaken IDs of things I have already seen). Here is a bit of video I took on my phone which gives a better idea of how great this was.

Nancy was also excited to see this rare – anomalous – Pacific White-sided Dolphin, that was more White than White-sided.

Elated, we carried on in search of Killer Whales, record numbers of which had gathered in the bay over the past week.  An hour or so later we found a group of 20 and spent the afternoon following them.  These Bigg’s (Transient) Killer Whales patrol the west coast of North America. They are specialist marine mammal hunters and will turn out most probably to be a different species to the inshore – primarily fish eating – Killer Whales of Vancouver Island.

Just fabulous. I think Nancy would have stayed out until dark with the whales, but some of the passengers had others plans to we headed back to the wharf, stopping for 20 minutes to watch a mother and calf humpback having some fun tail-slapping.

We got in about 7pm – a wonderful day at sea.

But the day wasn’t over. Venkat Sankar – who was super helpful all weekend giving me real-time info on where to find various rodents – recommended I could look for California Pocket Mice and Narrow-faced Kangaroo Rats up the Carmel Valley.  I was too lazy to spotlight, but did set a few traps in chapparal right next to the Carmel Valley road, near the junction with Tassajara Road.  This turned out to be a great area for small mammals.  The next morning, my 20 traps had caught 11 animals from 5 species.

And what I later realised was a Pinyon Mouse, and another lifer. If its ears had been sticking up straight I think I would have identified it straight away.

Before flying back to New York I took a spotlight stroll around the wonderful Pinnacles National Park, primarily looking for Narrow-faced Kangaroo Rats.  I didn’t find any of them but did get a brief look – but no photos – of my first Dusky Footed Woodrat, in Bear Gulch Cave, not far from the reservoir.  Driving the Panoche Road didn’t produce a great deal other than some Heerman’s Kangaroo Rats and a Desert Woodrat, plus Blacktailed Jackrabbits, Desert Cottontails, San Joaquin Antelope Squirrels and California Ground Squirrels, but not the San Joaquin Pocket Mice or Grasshopper Mice I was hoping for.

A very big thanks to Venkat Sankar for answering all of my many questions instantaneously over the weekend, to Vladimir Dinets for alerting this blog to the activity in the bay,  and also to Nancy Black at Monterey Bay Whale Watch for some of the best cetacean watching ever. Way to go California.

    Absolutely fantastic post!!! I can scarcely believe how many mammals you have seen. My list is barely over 50 species! I find it amazing that you were at the intersection of Carmel Valley and Tassajara Rds recently. I was there on April 27th to see my first Yellow-billed Magpie!

  2. heavenlyjane Says:

    So glad you hit pay dirt.

  3. mattinidaho Says:

    Congrats on 1,500, Jon! A major mammalwatching milestone. This looks like a fantastic trip too. Enjoyed Rhode Island report as well.


  4. Andrew Block Says:

    Very cool Jon. I love the shot of the albatross in the killer whale shots:-) That’s an awesome bird to get. Too bad you’re not a birder:-)

    • vnsankar Says:

      The black-footed albatrosses are great, aren’t they! I remember seeing like 30 on a pelagic last year – almost forgot how special they were. Too bad I didn’t see any cool marine mammals (what I was really looking for) that trip though…

      • Jon Hall Says:

        Even I get a kick out of Albatrosses so it was;t totally wasted. The boat crew got quite excited when we had 3 Savin’s Albatross around the boat too… an uncommon amount. There is obviously a lot of food in that water at the moment!

    Awesome Jon! Congratulations! You are inspiring me to make a trip for the Right-Whale Dophins. You came all the way from New York and I am only a couple of hours from Monterey Bay.

    What a milestone!!! Is it your most memorable? ……mac

    • Jon Hall Says:

      Thanks Mac and Venkat. It was a great way to mark the milestone .. whenever I really passed it. And yes, those dolphins were a quality sighting and I was lucky to get some cool pictures (one of which has gone moderately viral with thousands of likes and hundreds of shares). I still don’t think I will ever beat Giant Panda, but if I get charged by an Okapi with a Giant Pangolin on its back I will stand corrected 🙂
