California, September 2012 - Monterey Bay and Sea Valley Pelagic

In stark contrast with the pelagic out of Bodega Bay, this pelagic left Monterey with an  overcast sky and an oily calm, millpond like sea. We exited the harbour slowly, so that we could view the seaward side of the breakwater in search of waders, and were rewarded with Black Turnstones and Surfbirds, and Black Scoter, Pigeon Guillemot and Common Murre on the sea.

Black-vented Shearwater

The calm conditions were ideal for spotting small birds on the water and we were soon picking up Red-necked Phalaropes, Rhinocerous and Cassin's Auklets, the latter being extremely nervous of the boat and taking flight before we got anywhere near them. As we headed out to sea we started seeing our first shearwaters, initially Sooty, but quickly followed by Black-vented. This small shearwater, is dark brown above and white below, but as the name suggests has dark undertail coverts. We were advised to make sure we got a good look at these birds since it would probably be the only ones we saw, there were three in total, but we did in fact see more, or the same three on the way back in.

Pink-footed Shearwater

Continuing out we picked up more shearwaters in the wake of the boat, Sooty's were the most numerous initally, but were soon being replaced by Pink-footed and then a few Buller's appeared. There were many more Buller's out of Monterey that there was out of Bodega, but despite their often close views it was difficult to get any decent photos due the poor light.

A small group of Pacific White-sided Dolphins came into the ride the bow briefly and then it was back to the birds as a Flesh-footed Shearwater came into the wake. I had seen this species before in New Zealand, but don't remember appreciating its lumbering flight, which was more reminiscent of Cory's Shearwater. This bird stayed with us for a while and I was eventually able to get some acceptable record shots.

During this pelagic we were also able to see some visible migration and had a few land bird species visit the boat. A small group of Lesser Goldfinches circled and attempted to land before heading off, as did a Red-winged Blackbird, but the bird that drew the most attention was an exhausted Red-breasted Nuthatch. This bird initially landed on a pole hook, before deciding that the best looking habitat on the ship was someones fleece hat, whilst they were still wearing it. This bird was eventually captured and released in a nearby park back on shore.

The calm conditions made for excellent viewing of marine mammals and fish, and we saw five species of cetacean, Humpback Whale, Risso's and Pacific White-sided Dolphin and Dall's and Harbour Porpoise, plus got some excellent views of Ocean Sunfish. We had seen brief Humpback Whale blows on the way out, but the animals dived as we approached and did not resurface, whereas on our return to harbour two animals put on an excellent show. One of them was rolling around in kelp, and then swimming through it, presumably using it to remove parasites, or deal with an itch!

Humpback Whale blow. Much of the literature describes the blow of
Humpback Whale as being variable, tall, vertical and bushy, but all of the
Humpbacks we saw gave the 'V' shaped blow as pictured above.
Apparently this type of blow is more typical of North Pacific Right Whale,
but it would appear that is not the case in Monterey bay.

We had two encounters with Dall's Porpoises, one group of three and then a group of 12. This species is so fast, that it makes photographing them really tough, even in a millpond like sea.

By contrast the Risso's Dolphins that we saw just effortlessly glided through the water as if they didn't have a care in the world, making very easy photographic subjects.

The Ocean Sunfish were massive, certainly the biggest I had ever seen, it is difficult to gauge size in the image below but they dwarfed the accompanying Western Gulls. They have a laterally flattered body and apparently attract a large number of parasites, which is the reason they have a tendency to float on the surface. By doing this, they allow gulls to feast on the parasites that have accumulated on them, which is a great example of a mutually beneficial relationship, whereby the gull gets food and the Sunfish has its parasites removed.

This Ocean Sunfish was massive, but it is difficult to see that without
anything for size comparison, you will just have to take my word for it.
This group of at least a dozen young Ocean Sunfish had attracted
numerous gulls who were getting quite excited at the prospect of a nourishing feast.

Other bird species seen included Parasitic, Pomerine and South Polar Skua and a handful of Sabine's Gulls, one of which was a cracking adult.

Returning back into Monterey harbour we were greeted with excellent views of a Southern Sea Otter with her cub. The mother was obviously used to boats and didn't really pay us too much attention, but the pup was much more wary, and made sure mum was positioned between us for protection.

So that was the end of my second pelagic with Shearwater Journeys, a much calmer affair than the first out of Bodega Bay and not as much excitement. But it still produced an excellent mix of good birds and marine mammals, and was every bit as enjoyable. The trip was billed as Monterey Bay and Sea Valley and Storm-petrels, but we did not see a single Storm-petrel, but then I think I had had my fill further north. Both of my trips with Shearwater Journeys have been excellent, and I would still urge anyone coming to visit the west coast of California to book on at least one.

California, September 2012 - Bodega Bay and the Cordell Bank Pelagic 21st Sept

Well this was the day I was scheduled to go out on my first pelagic of our trip. I had booked this trip months before and had partly based our trip itinerary around it, and was pretty excited about what seabirds and cetaceans we might encounter. Fortunately I was blissfully unaware of the debate the day before about whether the trip would go ahead, but when I returned to our accommodation that evening, the first email I saw was from Debi Shearwater, it was titled 'WE ARE A GO!!', scrolling down I then saw all the others discussing the offshore wind and heavy seas, and the predicted forecast. The weather to me looked great, clear sky, warm sun but a stiff breeze in the afternoon, foolishly I didn't appreciate that a stiff on shore breeze, and winds from the north-west meant for high seas 30 miles out on the Cordell Bank! But it didn't matter now, we were going!

Our day began with a pre-dawn start at the Mariner off Bay Flat Road, Bodega Bay, and after our safety briefing we headed out to sea on the New Sea Angler, I didn't ask what had happened to the old one! The sea in the harbour was like a mill pond so it was difficult to understand what all the fuss had been about, but nevertheless I listened intently to Captain Rick Powers' warnings. Birding in the harbour was good with American White and Brown Pelicans, three Black-crowned Night Herons, two Belted Kingfishers and my first Black Turnstones of the trip. The intertidal was full of waders too, but with no scope and a moving platform there was no point in trying to identify them all.


Pink-footed Shearwater

Out of the shelter of the harbour the swell began to increase along with the numbers of seabirds, initially it was just Common Murres and Red-necked Phalaropes, but before long we were seeing our first Sooty and Pink-footed Shearwaters.

We were spoilt on this trip, because as well as Debi Shearwater and Lisa Hug we were graced with the presence of two of the leading Californian seabird experts, Todd Mcgrath and Steve Howell, Steve is the author of the recently published Petrels, Albatrosses, & Storm-Petrels of North America which I urge anyone interested in seabirds to get.

After a steady trickle of shearwaters that included more Sooty and Pink-footed and our first Buller's, we were visited by our first Black-footed Albatross of the trip, and at the same time a group of Pacific White-sided Dolphins and two Humpback Whales.

I didn't know which way to turn, but eventually things settled down as the dolphins and albatrosses stayed with us for a while. It was so tough trying to photograph things as the swell had really picked up by now, standing up was only possible whilst holding onto the side, so I had to wedge myself into a corner in order to let go and get some shots.

which is apparently from the French Frigate Shoals.,
unfortunately its not possible to read the whole number.

The albatrosses were coming in very close, several landing on the sea near the boat, one of these birds had a yellow colour ring with black writing, on its right leg. It appears, according to Monterey Bay Whale Watch, that birds with this combination come from the French Frigate Shoals, which are over 2700 miles away. For those interested, other Black-footed Albatross leg bands are from the following locations: Black/white letters - Kiaulea Point, Blue/white letters - Laysan Island, Purple/white letters - Kaena Point and Green/white letters - Kure Atoll.

Whilst engrossed in trying to get more photos of the albatrosses a close Buller's Shearwater passed the boat, quickly followed by a Hawaiian Petrel. It all happened so quickly, as I was focusing on the Buller's, Todd Mcgrath hollered from the back of the boat, I looked up saw the bird and quickly grabbed a few shots as it passed, unfortunately it didn't return! This is a mega off the Californian coast so it was great to get some shots, for the American Birding Associations Rarity Committee.


Hawaiian Petrel

The seas were getting pretty rough now and a couple of smacks on the side of the boat by a large wave made us all concentrate on holding on again, albeit with a little bit of smugness at our recent finding. We were heading along the Cordell Bank, to an area where the captain had recently seen hundreds of petrels, when a Black Storm-petrel flew past, then a Fork-tailed and then an Ashy. Before long, and with the help the menhaden oil slick, which the captain ordered we put out, we were soon surrounded by the largest number of storm-petrels I have ever seen in my life! There were thousands, they appeared to be mainly Fork-tailed, with Black being the second most numerous, then Ashy, there were even a few Wilson's for good measure.

The sea was alive with storm-petrels literally riding the crest of waves, then drifting up off the surface before settling back down on a calm area of water, hundreds were constantly streaming past the stern over the menhaden oil slick...it was simply spectacular. I tried so hard to get some shots, to try and convey what we were seeing, but bouncing around on a very rough sea made it pretty tough....I'm glad I took my sea sickness pills!

With the wind speed picking up and the seas stacking up it was time to head back. I couldn't believe what I had just experienced and we were still adding new species, Pomarine and Long-tailed Jaegers were regular, with occasional Parasitic (Arctic), a few Red (Grey) Phalaropes, Rhinoceros and Cassin's Auklets, Pigeon Guillemot and then a species of cetacean that had always been high on my wish list...Dall's Porpoise. These stocky black and white porpoises are just stunning and so fast, they are like mini Orcas. I tried so hard to get some shots but the rough sea and unstable boat made it just impossible, so I settled down and watched them ride to bow.....amazing!!


Black Storm-petrel

Safely back in Bodega Bay the talk was all about the Hawaiian Petrel, a very good bird off the coast of California, and one that so many of the American birders on board had wished for. But for me, whilst the moment of the passing Hawaiian Petrel had been exciting, so many of the birds I had seen were new to me, and the spectacle of seeing thousands of storm-petrels in such dramatic seas will live with me forever. I was so excited about this trip that I immediately booked myself on a trip out of Monterey Bay the next week, but that's for a later post. Debi Shearwater and her teams ID skills and Rick Powers, with his mastery of the sea, were fantastic, if you love sea birds you have to come to California and take a trip with Shearwater Journeys. For details of the numbers of different species seen on this trip check out Debi Shearwater's Blog. Our trip ended with a fly by from some hopeful Brown Pelicans who foolishly thought that we had been fishing.
