Tuna Fishing and Marine Wildlife 7/31/22

 This past weekend a friend invited me to join him on his boat for a tuna fishing trip.  I didn’t hesitate to take his offer.  The trip offered me two of my favorite activities - fishing and wildlife viewing.  Luckily, the weather, the tuna and the marine life all cooperated for me.  We caught yellowfin tuna and saw plenty of dolphins, whales and a few pelagic birds.

We left my friend’s dock at around 1 a.m. aboard his 36-foot fishing boat.  The boat, all decked out with offshore fishing gear, headed out of Barnegat Inlet on a course about 90 miles to the northeast.  We arrived at the fishing grounds around 5:30 a.m.  I can’t identify the exact location because my friend, like any other dedicated fishing captain, doesn’t give out his secret GPS coordinates.  But eBird decided to place my checklist in New York waters.

We would spend the day trolling the area, but it didn’t take long for us to see marine life activity on the surface.  As expected, Wilson’s storm-petrels were the first birds to show.  The small black and white birds appeared a few at a time and morphed into dozens bouncing off the water's surface.  Captain John calls them tuna chicks.  Soon after, I spotted a few great shearwaters on the horizon, backlit by the rising sun.  Not too long after, we spotted a frenzy of activity ahead of the boat.  There were birds gathered, shearwaters and storm-petrels, with dolphin cruising through the area.  Then we saw blow spouts in the distance, indicating that whales were there.  There was bait (which turned out to be sand eels) near the surface and the birds, dolphin and whales were converging into a big feed.  Captain John knew that the tuna would also join in on the chow down.

As we got closer, I could make out great shearwaters by the dozens, with a couple Cory’s shearwaters mixed in, flying and sitting on the water. Short-beaked common dolphin also by the dozens were zipping through the area, at times in front of, behind and alongside the boat.  But the showstopper was the humpback whale that was poking its head up through the frenzy.  I presume the whale was feeding and spy hopping, a move where the whale positions itself vertically in the water with its head out of the water to check out its surroundings.

The dolphin and whale show continued throughout the day.  During the whole day, I estimated there were at least four humpback whales and two, maybe three, fin whales in the area.  My estimate was based on seeing multiple spouts, and different colored bodies.  They were not shy of the fishing boats in the area and, likewise, the fishing boats gave the huge mammals their space.  We trolled in loops through the area most of the day, so there were periods of slow activity and periods of increased activity.  In one of the feeding forays, we saw a few shark fins mixed in with the action.  At one point a rather large shark swam near the boat.  The best photo I could get was its fin slicing through the surface of the water.  Captain John, from his spot up top of the boat, was able to identify it as a tiger shark.

Everyone on board the boat caught a yellowfin tuna, but by 2:30 in the afternoon, the tuna bite had tapered off and it was time to take the four-hour ride back to the dock.  As we pulled away, I could still see some blow spouts off the stern’s horizon.  It was a good day.  I caught some fish, saw some birds and saw some of the biggest and most intelligent creatures in the sea.  I can’t wait for my next day out on the ocean.

Birds of Island Beach State Park in Print

Image
     Over a year ago I started a project to document all the birds recorded at my favorite spot, Island Beach State Park in Ocean County, NJ.  I wanted it to be in book form so that my work would be available to the public.  Since I wanted to be in full control of the project, and work with my own timeline, I chose to use one of the self publishing companies available on the internet.  I chose to format the book as a summary account of all the birds found at the park, instead of a field guide.  I used available data from several sources, such as eBird , New Jersey Birds Record Committee and historic bird banding records.  When all the research was done, the final tally was 350 full species for the park. Front and back covers.   © S. Weiss The birds were presented in the latest taxonomical order with both common and scientific names.  Each bird’s abundance is described, such as common , scarce , rare , historical , etc.  The mo...

24 Hour Cape May Pelagic, 6/18-6/19- Skua, Jaeger, Beaked Whales, Devil Ray, Hammerhead Sharks and more

     Just a few days after returning from a Bahamas cruise, I headed down to Cape May for a 24-hour pelagic trip aboard the American Star .  We left the dock at nine in the evening to make our way out about 90 miles offshore.  After about an hour I decided to turn in for the rest of the night.  The boat is set up for daytime whale and dolphin watching tours, so there are no real sleeping quarters on board.  I enveloped myself in a sleeping bag on a metal bench on the upper deck.  The bench was only as wide as me, so it was not a comfortable night.  The sea conditions were not bad, but I catnapped through the night ride trying not to roll off the bench.  Around five o’clock, daylight started to break up the night sky and people began emerging from their makeshift beds.  I’m sure those who brought beanbag cushions slept much better than I did.  Either way I survived the night and the day ahead turned out to be well worth the ride...

Pileated Woodpecker 3/22/23

Image
      According to eBird, there are 400 species of birds on the Ocean County, NJ list.  This lofty number includes vagrants, one-day wonders and historical records (the latter is what I refer to as those that were last seen before the year 2000).  The list also does not include exotic species and escapees.  The list does include a few ghost birds ; birds that I know are around, but they seem to always elude detection.  One such ghost bird in the county is the Pileated Woodpecker.  A few live in the western portion of the county, particularly around New Egypt in Plumsted Township.  Most of the birders around here know where to look for them, but most search attempts are usually futile.  Today, I lucked out.  I went to one of their “known” locations and was able to see one and hear another.
