A Win for Forage Fish, and the Birds that Eat Them

A Win for Forage Fish, and the Birds that Eat Them

This post is reprinted from Audublog, the blog of Audubon California. GGBA’  incoming Executive Director Mike Lynes helped draft Audubon California’s comments to the California Fish and Game Commission on the importance of protecting forage fish — small species that are eaten by larger fish and other predators.

Small fish are a big deal for seabirds like the Brown Pelican and the Black-footed Albatross. That is why Audubon California and other conservation groups are applauding the California Fish and Game Commission’s unanimous approval [in early November] of new policies governing the harvesting of small fish – such as anchovies, sardine, herring and squid – that are vital to the survival of birds and wildlife.

“Seabirds and other marine wildlife in California are safer today as a result of this new policy,” said Anna Weinstein, seabird program manager for Audubon California. “These small fish are the heartbeat of our coast and ocean, supporting our diverse array of seabirds and other marine wildlife.”

The policy comes at a critical time. Forage species have gone from 40 percent to 80 percent of total landings in commercial fisheries in California. Market squid is now the most lucrative commercial fishery in California, reflecting increasing global pressure on forage species as larger fish have declined or disappeared.

“Seabirds are especially sensitive to changes in prey abundance, and their populations have crashed and not recovered in areas where overfishing takes place,” added Weinstein. “Now, the state of California, which manages a substantial part of the range of many wide-ranging birds and wildlife, has gone far to ensure that in the future there will be sufficient prey for our marine wildlife.”

The policy prevents the expansion of existing fisheries or the initiation of new fisheries until more is known about the needs of predator species such as seabirds, sharks, tuna and sea otters, and that these needs can be explicitly included in fisheries management plans. Catch quotas on currently fished species such squid and herring will not increase without first ensuring enough is set aside for predators.

The policy puts similar conditions on the development of new fisheries on currently unfished species such as sand lance, an important prey item for California breeding seabirds like Common Murre, Tufted Puffin and Marbled Murrelet.

The policy adopted by the Commission was submitted by a working group comprised of fishing industry representatives and conservation groups, including Audubon California, Oceana, the Natural Resources Defense Council and Ocean Conservancy.…

James Bond, birder

James Bond, birder

By Ilana DeBare

You’d never guess it from the box-office-blockbuster Skyfall, but…

James Bond was a birder.

No, not the Daniel Craig, Pierce Brosnan, Sean Connery secret agent Bond. But the James Bond who was an eminent American ornithologist, an expert in Caribbean birds who wrote the definitive Birds of the West Indies field guide.

In fact, Ian Fleming named his secret-agent-Bond after the birder.

Wikipedia writes:

Ian Fleming, who was a keen bird watcher living in Jamaica, was familiar with Bond’s book, and chose the name of its author for the hero of Casino Royale in 1953, apparently because he wanted a name that sounded ‘as ordinary as possible’. Fleming wrote to the real Bond’s wife, “It struck me that this brief, unromantic, Anglo-Saxon and yet very masculine name was just what I needed, and so a second James Bond was born.”

Birds of the West Indies by James Bond, 1936 edition

Fleming initially used Bond’s name without permission, according to a 2008 article by Katherine Tweed in Audubon magazine. Apparently Bond didn’t notice until several years had passed — at which point his wife wrote a furious letter to Fleming. The novelist apologized and said he viewed Bond’s field guide as “one of my bibles.” He later invited the Bonds to stay at his Jamaican estate.

The real Bond was born in Philadelphia in 1900. His interest in natural history grew out of a trip taken by his father to the Amazon in 1911. Later he studied at Cambridge University, worked briefly as a banker, and then joined the staff of Philadelphia’s Academy of Natural Sciences, eventually becoming its curator of birds.

Since Bond first published his Birds of the West Indies in 1936, it has been reissued several times, including as a Peterson Guide. Bond died in Philadelphia in 1989.

Wikipedia notes that, “In his novel Dr. No, Fleming referenced Bond’s work by basing a large Ornithological Sanctuary on Dr. No’s island in the Bahamas.”

In the 2002 Bond film Die Another Day, the Pierce-Brosnan-Bond is seen examining Birds of the West Indies in an early scene that takes place in Cuba.

Later in that film, Brosnan introduces himself to the Halle Berry character as an ornithologist. It was, of course, a false identity.

But not quite as false as most movie viewers assumed.

Report from Hawk Hill, Part 2

Report from Hawk Hill, Part 2

Each fall, hundreds of volunteers with the Golden Gate Raptor Observatory track hawk migration through the Bay Area. To celebrate fall migration, here’s the second installment in a two-part interview with GGRO Director Allen Fish

—————————

Q: What trends have you seen in recent years in terms of numbers, species, timing, anything else?

A: With 19 species of annual raptors, and a quarter-century of data, I could spend days on this question, but to give a few examples:

  • Peregrine Falcon numbers have increased steadily over the 25 years of the GGRO count.  In 1985, we tallied one Peregrine every 200 or so count-hours at GGRO; today we see a Peregrine just about every other hour.
  • We have started to mine our data for phenological changes — that is, changes in peak dates of migration that might be attributed to climate change.  Sharp-shinned Hawks seem to show some slippage of their peak dates over time, but the statisticians are still working on their part of the analysis, so I better not say too much.

Q: How many volunteers do you have counting on weekdays? On weekends?

A: Weekday counters, about 80 volunteers.  Weekend, about 60.  A volunteer makes a commitment to one weekday or weekend day every other week from August through December.  An exceptionally experienced volunteer with five to 25 years’ experience is the leader for the day.  He or she tries to see and corroborate every raptor.

Q: How does the Quadrant System work? Does it keep you from counting the same hawk multiple times? How was it created?

A: We split the 360-degree view-shed on Hawk Hill into four impossibly huge slices of pie that we call quadrants.  Two to three volunteers focus on one of these quadrants for an hour at a time trying to see every new raptor, and to pass every previously spotted raptor.  If we’re not sure whether a hawk has been counted already, we count it.  One person records species, ages, and sexes for the whole team.

Nothing can keep a human being from counting the same hawk multiple times on Hawk Hill.  We have learned from band recoveries and radio-tracking studies that raptors may leave Marin and come back days or even months later.  So how do we account for “double-counts?”  First off, we assume they happen.  And that they happen at some regular rate that stays consistent from year to year. …

Report from Hawk Hill, Part 1

Each fall, hundreds of volunteers with the Golden Gate Raptor Observatory track hawk migration through the Bay Area. From the top of Hawk Hill in the Marin Headlands, they spot and count raptors that are following the coastline south and then swerving inland when they reach the Golden Gate. GGRO’s Hawkwatch program is one of the unique treasures of Bay Area birding. To celebrate fall migration, here’s the first installment in a two-part interview with GGRO Director Allen Fish

————————–

Q:  When does hawk migration season “officially” start, peak and end??

A: Most years we start to see the early migrants – young Redtails and Osprey in particular – right around the first of August.  We long ago made a decision that we would start to count and band right around August 15th and carry our daily studies through at least the first full week of December.  Although, on the back end, some raptors, Redtails and even accipiters are still moving through until the first week of January.  Probably because of the moderate winter climate here, some raptors have a great deal of behavioral flexibility about when they move.  Some of this movement may not be classical migration, but would be more described as dispersal, that is, an ecologically-stimulated movement.

In terms of numbers of hawk-sightings, the highest flight-days of the season have fallen in a date-slot from about September 15 to October 8. However. the peak day usually hits in a smaller range of September 25-30. This peak is usually driven by Sharp-shinned and Cooper’s hawks. The big migration period — which tends to stay above 120 raptors per hour  and may peak at ten times that — lasts through about November 10.

Q: About how many raptors are sighted on a typical day at the peak of the season?

A: Our peak days have ranged from about 600 sightings per day (six hours of counting per day) all the way up to 2,800 sightings per day.  That was on September 21, 1984.

Q: Which species are most common?

Turkey Vultures, Red-tailed, Sharp-shinned and Cooper’s Hawks together make up 87 percent of the flight.  Fifteen other species of diurnal raptors are seen most years.  We’ve seen Mississippi Kite on three occasions since 1976, and a Eurasian kestrel was banded here in 2007.

Q: Where are they coming from and going to?
