SANTA CRUZ ISLAND JAY
Santa Cruz Island Jay (Aphelocoma coerulescens insularis) was first described by Henshaw in 1886. It is found on Santa Cruz Island, and nowhere else. This jay is a third again as large as its mainland counterpart, and a much brighter blue. In 1920, ornithologist William Leon Dawson wrote:
- “There exists upon the Island of Santa Cruz, some 25 miles distant from the mainland at Santa Barbara, a jay which is almost an exact replica of the mainland bird in color and pattern of plumage, but which has undergone certain important modifications of proportion, especially of beak and feet.”
There are at least 35 historic skin specimens in the U.S. National Museum of Natural History:
- 1875 (4) H. W. Henshaw (one discarded in 1957)
- 1889 (5) C. H. Townsend, U.S.S. Albatross
- 1892 (17) Clark P. Streator

1886 Santa Cruz Island: Eli Whitney Blake, Jr. visited Santa Cruz Island twice in 1886: from July 4-July 24, and again August 6-September 3. During his visits, Blake camped in a canyon near Platt's Harbor. He noted:
- Aphelocoma insularis. Island Jay. — By far the commonest land bird of the island, and familiar to the verge of impudence. General habits like those of its near relatives on the mainland. Several nests which must have belonged to this species were placed in trees or bushes between six and thirty feet from the ground. They exhibited no marked peculiarity of construction.
1892 Santa Rosa Island: In July 1892 C. P. Streator, during a visit to Santa Rosa Island, made a notation in his field notes: “ Aphelocoma. Mr. John More informs me that there are jays on the island.” There is no scientific evidence to support the historic presence of jays on Santa Rosa Island.
1897 Santa Cruz Island: “With much interest I read Mr. Jos. Mailliard's article on the birds of Santa Cruz Island in the May-June number of the Bulletin, and finding his experience different from mine in some particulars, I submit a few notes taken principally on the west end of the island in May, 1897... A Flickers ’ nest was seen in a tall dead tree in the bottom of the canon and farther down this canon I found the Santa Cruz Jays nesting. ...”
Beck, R.H. Additional Notes on the Birds of Santa Cruz Island, Cal., 1899
1898 Santa Cruz Island: “...Naturally enough a sight of the Santa Cruz Jay (Aphelocoma insularis) was eagerly desired, but it was some days before one was seen. There were no Jays within a mile or two of this harbor [Scorpion Harbor] but some were found where the first brush commenced on the steep hillsides toward the head of Scorpion Canon. In fact they were quite numerous among the brushy hills but were very difficult to approach, more from the nature of the ground than from their wariness, though they were here comparatively shy. Their harsh notes could be heard on all sides among the bushes, but seldom near enough to shoot. Two were taken at last in the canyon, but all the rest that fell to my lot were captured at La Playa [Main Ranch]. The notes of this Jay are much harsher than those of the California Jay (Aphelocoma californica), the screech being more like that of Cyanocitta stelleri and the bird much larger and of brighter and deeper plumage... The main ranch... In this locality the Santa Cruz Jay was very abundant and bold. Many were shot with the auxiliary barrel, being too close to use a larger charge. In some particular tree these birds would at times be very numerous, flying singly, by twos or threes, and then again hours might pass without a Jay being seen. Every accessible bush and tree within two or three miles of Laplaya [Main Ranch] was carefully searched for their nests, but, while many old ones were discovered, only five were found occupied. Two of these contained eggs, one set of three eggs and one set of four; two contained young, two fledglings in one nest and three in the other, while the fifth nest was placed near the end of a long slim branch of a large live-oak, with no means of reaching it. From the small proportion of new nests to old ones discovered, it would seem that either the birds were not breeding to any extent this year on account of the severe drouth perhaps, or else nests when once built must last in that locality about I00 years before disintegrating... Following is a list of birds observed during my stay:- Santa Cruz Jay (Aphelocoma insularis);... ”

1907 Santa Cruz Island: “Aphelocoma insularis. Santa Cruz Island Jay. Abundant except on northwestern portion of island. Those seen in the vicinity of Cochas Pietres [Coches Prietos] were nearly all females. In the higher pine region this order was reversed; only two or three females observed.” [“At 11:30 p. m., November 19, 1907, my father (H. Linton), Mr. George Willett, and myself left San Pedro harbor in a dilapidated fishing smack and in company with a crawfisherman, one “Cold-foot” Jorgensen. We arrived off the south end of Santa Cruz Island at 10:30 the following day during a stiff norwester. For various reasons we were unable to make camp until the 22nd. It may not be amiss to state here that twice during the blow we were nearly wrecked: once while at anchor in Potatoe Harbor, a broken anchor allowing the boat to drift within the breaker line and nearly onto the rocks. In this instance the timely arrival of Willett and H. Linton in a small boat, saved the day, and incidentally the fishing smack. At another time (the engine having broken down) we were blown nearly onto the rocks of Anacapa Island; but with father at the wheel and Willett and I on the “sheet” we managed to hold her off. I mention the foregoing, and the many sleepless nights spent on the rocky shores, “running” the surf several times each day (with attendant duckings), etc., merely as a warning to those who seem inclined to believe a field naturalist’s life “strewn with roses”.

April 30, 1897 [Condor 1(1):6]: “Nesting of the Santa Cruz Island Jay. On the 30th day of April, 1897, I was landed on the west end of Santa Cruz Island and for five days busied myself in collecting and caring for the few species of birds found within a few miles of camp. I had been hoping to find the Santa Cruz Jay nesting, but until the forenoon of the 8th of May not a bird had been seen. On that day, after a long walk up the bottom of a canon, the first Jay was seen perched on a dead willow stump a short distance ahead, and was at once laid away in my basket out of the hot sun. A 20 minutes’ search among the bushes and small trees nearby revealed a nest in the thick top of a scrubby oak, on the steep side hill and on a level with my eyes. A careful approach showed the female on the nest where she remained until my hand was but inches from her. She then flew to a tree forty yards off, from which she too was laid away with her mate. The nest contained two eggs and was the counterpart of a California Jay's nest, being composed principally of oak twigs and lined with rootlets. The next day, after a long steep climb over rough hills, a second nest was found near the bottom of a rocky canon in a tangle of bushes. The birds were heard calling on the hill above the nest, which, after a short search, was located. It was similar in construction to the first and contained three eggs. A half mile farther down the canon another nest was found near the end of an oak limb, fifteen feet from the ground and contained two young birds. The location, material and size of this nest was very similar to that of the Blue-fronted Jay in Santa Clara County, Cal., so much so in fact, that I had to tear it slightly to make sure there was no mud in it. The birds were absent when I climbed out to it, and I thought it possible that the Blue-fronted might occur on the Island. A few hundred yards farther a nest was seen in a willow tree near the stream, twelve feet up. The bird remained on until I nearly touched her, when she flew across the stream and called her mate, who came and silently watched me a short distance away. The silence of the Island Jays was very noticeable, and except for their habit of perching in conspicuous places, might have prevented their discovery. Judging from the four nests examined, two or three eggs would seem to be an average set. The eggs are somewhat larger than the average eggs of A. californica. Those obtained measure: (Set ½); 1.21x.85, 1.18x.84. (Set ⅓); 1.15x.90, 1.18x.90, 1.18x.92. (Set ⅔); 1.10x.86, 1.14x.88 1.16x86 inches. The markings are much lighter in color also, being light brown, grayish and lavender. R. H. Beck, Berryessa, Cal., Dec. 24, 1898.”
August 30, 1916 [SBMP]: “One of the most curious facts brought to light by the field work carried out this past season by the staff of the Museum of Comparative Oology is the effect of isolation upon the color of bird’s eggs. Isolation, that is, of the parent birds. Santa Cruz Island has a jay found upon the island only, and not even upon its neighbor, Santa Rosa. It is like the mainland type, our chestless blue jay, from which it undoubtedly spring, save that it is considerably larger and more deeply colored. An extensive series of the eggs of these birds collected this year shows almost absolute uniformity of coloring, whereas the eggs of the mainland bird, well distributed throughout California, are highly varied, and are rated among the handsomest in collections. The differences in the eggs of the mainland bird are so marked that two distinct types or “phases” are recognized - a “red” and a “green.” While the birds of the mainland stock themselves preserve a substantial uniformity of appearance, the great climactic variety of their setting, their environment, has reflected itself in the highly variable coloring of the egg. Diversity of stock, or a considerable development of the tendency to vary, is thus indicated. But the eggs of the Santa Cruz Island blue jay point as plainly to a uniformity of parental stock, to descent, in all probability, from a single pair of bords [birds]. The Santa Cruz Island colony of the crestless blue jay stock is closely inbred, while the mainland stock is highly crossbred. The evidence of the two series of eggs now reposing in the M. C. O. collection is so clear that he who runs may read.”
November 27, 2019 [Ventura Star]: “While its overall population numbers are just around 2,000, the island scrub jay’s impact on the world around it is enormous. By caching thousands of acorns every year, it has helped to restore Santa Cruz Island’s precious oak woodlands. California’s Channel Islands have proven to be a safe haven for a wide array of flora and fauna ever since the chain became a national park in 1980. Over the years, cooperative efforts by the National Park Service, The Nature Conservancy, the Institute for Wildlife Studies and other agencies have managed to bring Channel Islands National Park toward a natural balance. This is seen in the return of several significant avian species, including the peregrine falcon, California brown pelican and bald eagle. All three species were decimated by DDT pesticides but have made remarkable comebacks. Bald eagles, for example, were extinct on the islands for 50 years, leading up to 2002 when the first eaglets were returned to Santa Cruz Island. More eaglets followed through 2006, and after years of intensive efforts there are now roughly 70 bald eagles that have reestablished historic habitat across the national park. In 2019, America’s national bird experienced something of a baby boom: This year there were 19 breeding bald eagle pairs on the islands, producing a total of 24 chicks, with 10 chicks on Santa Cruz Island, nine on Santa Catalina Island, two each on Anacapa and San Clemente Islands, and one on Santa Rosa Island. Isolation has its advantages on the Channel Islands and with protections in place, it’s easy to see conservation at work. Once ranch animals were removed from the volcanic archipelago, much of the islands healed themselves, thus giving island endemics a chance to thrive. Still, more challenges lie ahead. One species of significant ecological importance is the endemic island scrub jay. Santa Cruz Island, the largest, most biodiverse isle off the California coast, is the only place in the world this passerine species exists. The island scrub jay evolved from its mainland cousin, the western scrub jay, thousands of years ago while surrounded by open ocean — first when the northern chain was just one island (named by scientists Santarosae), and ever since, beginning 20,000 years ago at the end of the last Ice Age. From there, sea levels rose 400 feet and the Northern Channel Islands were created. It wasn’t until 1994, however, that the jay became its own separate species, Aphelocoma insularis. Birders from all over the globe flock to Santa Cruz Island just to get a mere glimpse of the jay, a streak of brilliant blue amongst the island oaks, Bishop pines, manzanita, toyon, lemonade berry and eucalyptus trees. It is typically heard before being seen, with its rattling, guttural, raspy calls filling the rocky canyons, but there is no denying its bright Dodger-blue wings, smoky gray back and creamy white breast. Biologists from The Nature Conservancy, Cornell Lab of Ornithology and the Smithsonian Institute are currently in the middle of lengthy research projects involving the island scrub jay, which began in earnest in 2007. Although they’ve made several amazing discoveries about the species and its diversified habitats on Santa Cruz Island, biologists are also finding that there’s still much to learn about one of the rarest birds on the planet. “A fascinating, interesting and ecologically really important bird,” said Scott Sillet, a wildlife biologist for the Smithsonian Institute and its Migratory Bird Center. “There are a lot of unknowns surrounding this bird.” If you spend enough time on any of the islands, it can feel isolated out there, even though the Ventura County mainland is less than 20 miles away, with Los Angeles a mere 60 miles southeast. Yet, Channel Islands National Park is also known as “the Galapagos Islands of the North.” With over 60 endemic species, Santa Cruz Island possesses the greatest number of plant and animal species of all the islands in the park. Thousands of years of isolation on the Channel Islands forced endemic flora and fauna to evolve, with island species becoming larger or smaller (based on competition, diversity of habitats and available food sources) than their mainland counterparts. In the case of the island scrub jay, a natural phenomenon called “gigantism” has allowed it to grow larger by a third, with a beefier beak and a deeper blue color than its mainland counterpart and distant cousin. But it’s not just the isolation of the mountainous, 96-square-mile and 22-mile-long isle. Gigantism is also associated with a lack of predators. Sure, the island scrub jay contends with tree-climbing island foxes (another island endemic) and burly, ruthless ravens, but compared to what the western scrub jay endures on the mainland, the island variety looks over its shoulder far less. Competitively, the island scrub jay has no peers among other songbirds. Island scrub jays are mostly omnivorous, feasting within 10 different plant communities on a healthy variety of insects such as crickets and earwigs, reptiles such as side-blotched and western fence lizards, and even deer mice and other birds’ eggs. There’s a flipside to this isolation game. Even though Santa Cruz Island is the largest isle off the coast, the range of the island scrub jay is described as tiny. Its small population size of roughly 2,000-plus jays makes it vulnerable to natural disasters such as wildfires (most recently the 258-acre blaze in the island’s central valley in April 2018). Even more worrisome is disease, such as the West Nile Virus. The mosquito-carrying virus has been well-documented on the mainland, but as far as anyone knows, it has never touched down on the Northern Channel Islands. Due to these factors, the island scrub jay is listed as “vulnerable” by the International Union for Conservation of Nature (ICUN). Over the last seven years, a number of jays have been trapped and vaccinated, but the practice is labor intensive. “It harkens back to Wile E. Coyote and the Roadrunner,” said Sillet, referring to the classic Looney Tunes cartoons. “A peanut, string, stick and a box. If you like to fish, you’ll like to catch jays.” “They’re hard to catch, really smart and they don’t want to get poked twice,” said Scott Morrison, director of The Nature Conservancy (TNC) of California Conservation and Science Programs. “So there’s limitations on vaccinations. There’s a lot of field work involved. We could prepare to bring them into captivity.”
Trapping occurs a few times annually. Blood and measurements are taken, as are swabs from beaks extracted to check for disease. It’s about a 15- minute checkup. Some jays are fitted with GPS and radio tags. On neighboring Santa Rosa Island, several miles to the west of Santa Cruz Island, there is evidence of island scrub jays dating back to the late 1800s. Any effort to reestablish a population on Santa Rosa, the second largest isle off the California coast, would require a thorough study of the current population, its role in the food chain and how much food is available for them to thrive. The last population survey took place in 2008.
“At the moment we’re pretty confident that West Nile has not yet established itself on the island with residents and migrants,” continued Morrison. “Some birds have been tested. Some mosquitoes tested, but it’s a matter of when and not if.” I couldn’t make out what the jay was searching for. The cavity of an old, downed, bleached-out eucalyptus tree was captivating an island scrub jay. It was too busy thoroughly probing the cavity, so it didn’t mind me observing from just a few feet away.
After much probing, it finally emerged with its prize: an empty, nondescript snail shell. Then it proceeded to pin it down on the trunk of the tree and pummeled it open with its beak, extracting anything remotely nourishing from the vacant shell.
“They’ll cache anything,” said Sillet. “They don’t become satiated during caching mode. They put as much food away as they can to get through a winter.”
That includes island cherries and, more importantly, acorns from island oak trees. Santa Cruz Island possesses extensive island oak groves because island scrub jays are responsible for enhancing those groves on the craggy isle.
Contrast this with Santa Rosa Island, where the extent of oak groves is reduced, due to a combination of island scrub jays going extinct during the late 1800s and, possibly, cattle grazing up until the late 1980s. On this windswept isle, topsoil has been blown away by perpetual northwest winds.
Sillet said that the soil of island oak groves on Soledad Peak at 1,574 feet, the location of a cloud forest restoration site located in the middle of Santa Rosa Island, is so badly eroded that the exposed root systems of the oak groves resemble those of mangrove trees in the tropics.
It’s estimated that a single, mature island scrub jay caches somewhere between 3,500 to 6,500 acorns per year on Santa Cruz Island. The birds have the innate ability to immediately cache the ballistic-shaped acorns with their points down to generate growth in a dark, shady place. The embryo of the acorn is near the point. All that caching of acorns on Santa Cruz has reestablished its oak groves, especially following the eradication of thousands of ranch animals (sheep, pigs, cattle and horses) that ran amuck across the island’s rolling marine terraces, tranquil Central Valley and steep, rocky canyons.
Volunteers have tried to replicate on Soledad at Santa Rosa Island how jays disperse acorns on Santa Cruz. During one restoration project, 3,000 acorns were planted. It took 600 volunteer hours to perform the equivalent work of just one island scrub jay.
“I like to think their role is restoring oak woodlands,” said Morrison of the jays. “They’re ecosystem engineers and they have prolific memories. Pretty phenomenal recovery of vegetation on Santa Cruz Island and the jays have had a hand in it.”
The jay’s manner is scattering seeds virtually everywhere, efficiently distributing acorns across the island, and in particular moving seeds upslope. The number one water input on the islands is fog, so when acorns are planted upslope, the fog sweeps over the islands and the moisture catches in the leaves of the island oaks. From there it trickles into the ground and eventually the creeks. This is a much-needed remedy at places like Soledad Peak.
“This all gives communities a head-start on climate change,” continued Morrison. “I’m a big believer in a whole bunch of species benefit on the island.””
