Animals Available for Adoption

Nickname: Unnamed
Patron: None
Gender: Female
First sighted: 2018
Age class: Adult
Age: Unknown

This mama whale is a survivor! You can tell from the rake marks on her tail that she has been through at least one killer whale attack and survived. We spotted her in Guerrero, Mexico on March 10, 2018 with a calf by her side. It is rare to get fluke IDs for mother whales in their calving grounds, as their calves are usually not strong enough to make those deep dives that whales make when they show their flukes. But it was late in the season and her calf had gained enough strength to make deep dives along with her and they were getting ready to make their long journey north when we spotted them. This whale hasn't been spotted up north yet in her feeding grounds, so we still have a lot to learn about her

Nickname: Unnamed
Patron: None
Gender: Probable male
First sighted: 2011
Age class: Adult
Age: >7

This whale, a probable male, has been spotted in Guerrero, Mexico in 2015, 2016, and 2018. Every time we have seen WGRP175, it has been with a group of whales, most often in the role of an escort in a mother, calf, escort group. It was first identified by Cascadia Research Collective in the Farallon Islands off the coast of San Francisco back in 2011. This whale is special to the Whales of Guerrero Research Project because we spotted it at the very beginning of a five-year field survey and again on the last day of that same study in 2018. It seems to be very faithful to our region and we hope to continue seeing it again every year!

Nickname: Glen Curtis
Patron: The Schillerstrom Family
Gender: Probable male
First sighted: 2009
Age class: Adult
Age: >9

We spotted Glen Curtis, with its beautiful white Category 1 fluke on February 23, 2018 in front of the Morros, a small group of islands in front of the Mexican fishing village where we work and live. It was escorting a mother and calf, making it a likely male based on its behavior. Six months later, it was seen off the coast of San Francisco. It spent 2017 feeding in Monterey Bay and then was seen off the coast of Southern California, probably en route to the breeding grounds in Mexico. Glen Curtis has been spotted along the Mexican coast in Baja and near Puerto Vallarta, as well. It was first identified in Banderas Bay, near Puerto Vallarta back in 2009.

Nickname: Loie
Patron: Lois Butler Cavanagh's Family & Friends
Gender: Unknown
First sighted: 2004
Age class: Adult
Age: >14

Loie, WGRP184, has been spotted in both northern (Bodega Bay) and southern California (Santa Barbara), as well as in the winter breeding grounds of Guerrero in Pacific Mexico. Loie was first seen in 2004, and then again in 2006, 2007, and 2008 in its California feeding grounds. When we saw Loie on January 7, 2017, it was traveling with another (unknown) adult whale. They were traveling along in perfect synchronicity with each other, when Loie proceeded to breach! After that, there was lots of rolling around just below the water’s surface. What were they doing down there? Only they know…

Nickname: Sylvia
Patron: Genevieve Manise
Gender: Unknown
First sighted: 2010
Age class: Adult
Age: >7

When we saw WGRP264 on February 4, 2017 it was in fast pursuit and extremely interested in the other whale it was chasing. At one point, another whale tried to join in, but then quickly left. This whale has a classic category 4 tail – just some white patterns on the ends and all black in the middle. We think the patterns on its tail lobs are pretty neat. What figures and shapes do you see in there? This whale has been spotted in Monterey Bay at least twice by other researchers, in 2013, 2014 and 2015 and also in Southern California.

Nickname: Winnie
Patron: Carla Rossetti & Madeline Alonzo
Gender: Unknown
First sighted: 2013
Age class: Adult
Age: >5

Winnie (WGRP250) was spotted traveling alone along a beautiful isolated beach known as Turtle Beach (Playa Tortuga) because sea turtles nest there. Winnie has rake marks on its tail, which means it has survived a killer whale attack! Winnie jumped near our boat, and when it jumped, it shed some skin, which we scooped up and sent off to a lab to be analyzed. We are still waiting for the results, but the DNA in the skin of this whale will tell us if it is a male or female and more. This whale was seen twice in Monterey Bay, CA (in 2013 and 2016) before we saw it on January 29, 2017

Nickname: Boomerang
Patron: Council Rock Primary School
Gender: Unknown
First sighted: 2002
Age class: Adult
Age: >16

Boomerang whale is a traveler! This whale was first identified in 2002 and has since been seen in 2012, 2016, and 2017. Researchers have spotted it as far north as Oregon, USA and as far south as Sayulita and Banderas Bay in Mexico. When we saw Boomerang on January 11, 2017 in Guerrero, it was traveling with another adult whale. It has such a beautifully patterned tail that it took our breath away! We think its unique pattern is memorable enough to be easily recognized when it is spotted again.

Nickname: Finley
Patron: Kim King
Gender: Unknown
First sighted: 1988
Age class: Adult
Age: >29

Finley (WGRP124) had already been through a lot before Cascadia Research Collective first ID’ed it back in 1988. Those rake marks on Finley's tail indicate that it survived a killer whale attack, probably while still a calf en route from its calving grounds in Mexico. That irregular notch on the right side shows that Finley may have survived a fishing line entanglement, too! We spotted Finley for the first time in Guerrero, Mexico in 2015. It was with a competitive group of males when we saw it in Mexico. It has been spotted in Costa Rica and Nicaragua and repeatedly in Northern California.

Nickname: Melissa Ann
Patron: The Hanke Foundation
Gender: Female
First sighted: 1991
Age class: Adult
Age: >25

WGRP136, nicknamed Melissa Ann, is a mother! We spotted her with a tiny calf that also had a beautiful white tail in 2015 in Mexico. This is extra special because Melissa Ann has been sighted by Cascadia Research Collective in Nicaragua, Southern Central California, and in Monterey Bay, Año Nuevo, and the Farallones Islands (all in California), going back to 1991! This means that Melissa Ann, if she is like most female adult whales, has a calf every 2-3 years and is a part of the tiny Central American humpback whale subpopulation which number around 400 individuals. We hope to see this whale again with a new calf in Guerrero soon!

Nickname: Admiral Balaen
Patron: S. R. Sisson
Gender: Unknown
First sighted: 5 Aug 1996
Age class: Adult
Age: >21

Admiral Balaen (humpback whale ID WGRP130) has a severe case of wanderlust based on its re-sighting history! It has been spotted in California by Cascadia Research Collective and by whale watch guide Kate Cummings in the Pacific Northwest, and as far south as Nicaragua! This means that Admiral Balaen is part of the tiny subgroup of Central American whales, which are thought to number 400 individuals or less. We spotted Admiral Balaen traveling with another adult whale at the end of our research season in March 2015.

Nickname: Bowser
Patron: The Keenan Family
Gender: Male
First sighted: 20 Jan 2004
Age class: Adult
Age: >13

Bowser was spotted first in Banderas Bay, near Puerto Vallarta, Mexico back in 2004, and already had the fluke deformity that it still has today. The tail injury was probably caused by a net entanglement or ship strike. Bowser was spotted again in Banderas Bay in 2016, and has also been seen in Southern California by researchers and whale watchers 15 times. It is known as CRC10948 by Cascadia Research Collective. We spotted Bowser in Guerrero, Mexico, for the first time on January 30, 2017, vying with at least two other adult males for the right to escort a female humpback and her calf. Its regular fidelity to Southern California feeding grounds makes it a likely member of the endangered Central America subgroup, or distinct population segment, of humpback whales, which probably don’t number more than 450 total individuals!

Nickname: Canice
Patron: St. Canice's Catholic Primary School Katoomba
Gender: Unknown
First sighted: 25 Oct 2012
Age class: Adult
Age: >4

Canice (WGRP223) was in a competitive courting group of 4 adult whales when we spotted it in Guerrero on January 25, 2017. They spent several hours chasing each other through the bay and at one point a group of dolphins joined in the fray – they can’t seem to resist the action! We found a match for Canice's fluke and learned that Cascadia Research Collective has spotted this whale off the coast of Mendocino in Northern California once before, in October 2012. With that beautiful distinct white tail, this whale will be easy to spot when it shows up again, if we are ready with a camera!

Nickname: Dragon
Patron: Glenelg Country School
Gender: Female
First sighted: 16 Jan 2014
Age class: Adult
Age: >5

Dragon, humpback whale ID WGRP001, was the very first whale added to the Whales of Guerrero fluke identification catalog. She was seen on January 16, 2014 traveling in the company of a calf. We hope to see her again next year! Update: Cascadia Research Collective reported having seen Dragon before in 2011 and 2013 in two very different places—Costa Rica and Monterey Bay, California!

Nickname: Fran
Patron: Ferd Bergholz
Gender: Female
First sighted: 20 Jan 2014
Age class: Adult
Age: 9

Fran, humpback whale ID WGRP003, is the second whale for which we got a fluke ID (on January 20, 2014) and is the first one we matched to another catalog. When we visited our colleagues at Cascadia Research Collective in Seattle, we found out that Fran is no stranger to the research scientist's telephoto zoom lens. She was first spotted as a calf in 2005 in Moss Landing, California. Since then, she has been spotted and photographed 40 more times around Moss Landing, Monterey Bay, Half Moon Bay, and the Farallon Islands! So we know that Fran is 9 years old. She had never before been photographed in her winter mating grounds, so when we spotted her alone with a calf, we were able to add another piece to Fran's story—she's a mother! Not only that, she is the daughter of Kaplan Kids, a whale that has been known to Cascadia Research Collective since 1988 and was previously part of our adoptions program.

Nickname: Luna
Patron: The Roepstorff Family
Gender: Unknown
First sighted: 5 Feb 2014
Age class: Adult
Age: Unknown

Luna, humpback whale ID WGRP010, was first seen on February 5, 2014 traveling just outside of the city of Zihuatanejo, Mexico. There was a small group of rough toothed dolphins—a dolphin about which is little known—that seemed to be harassing Luna in some way. It was writhing around on the surface and acting "funny." We don't know if this adult whale is a male or female. In December 2014, we found a match for Luna's distinctive fluke in Cascadia Research Collective's catalog! This whale has been spotted by researchers in both southern California and Monterey, CA, with the first sighting in summer 2013.

Nickname: Humpfree
Patron: Monica Grzesiak
Gender: Likely male
First sighted: 14 Feb 2014
Age class: Adult
Age: > 5

Humpfree, humpback whale ID WGRP018, is probably male, although we can't know for certain unless we can see the underside of its belly or get a DNA sample. We suspect Humpfree is a male because "he" was traveling with a female whale and her calf, acting as what we call an "escort." Although female whales, which have a gestation period of 12 months, rarely become pregnant and give birth two years in a row, it's not uncommon to spot two adult whales and a baby traveling together for extended periods of time and, most of the time, the trio is comprised of a female, her calf, and a male. DNA samples of other similar groups show that the male is not the father of the calf. So why do adult male whales spend their time with non-receptive females when there are others they might have better luck with? We just don't know; maybe they're trying to score points for next year. It's another wonderful mystery of marine mammal science. The distinctive leopard spot pattern on this whale's tail will make it a fun one to try to spot again on the water next year and to look for matches in our colleagues' catalogs.

Nickname: Moyuan
Patron: Shimeng and Junqing
Gender: Unknown
First sighted: 18 Feb 2014
Age class: Adult
Age: 11

Moyuan, humpback whale ID WGRP019, was first identified by Cascadia Research Collective and photographed by John Calambokidis on September 1, 2003 just west of the Farallon Islands, and John photographed it again on September 13, 2010 in Monterey Bay, due west of Moss Landing. We don't know whether Moyuan is a male or female, but now we know that it traveled to Mexico after leaving its California feeding grounds in 2014.

Nickname: Hercules von Whalington, Esq.
Patron: Nicole Ciaccia
Gender: Male
First sighted: 24 Feb 2014
Age class: Adult
Age: 9

Hercules von Whalington, Esq. (WGRP021) was our first match with our colleagues to the south of us in Oaxaca and we were all so excited to confirm that the whales that visit Guerrero also travel further south and spend time in the state of Oaxaca. We also learned that this whale was born in winter of 2005, making it 9 years old. Now that we have a confirmed match between the two regions, we are looking forward to finding out how they travel between the two states. Our colleagues in Oaxaca took a DNA sample of this whale's skin in 2012, and after analyzing it they learned that this whale is a male.

Nickname: Ferdinand
Patron: Sandy High Aquanauts Club
Gender: Unknown
First sighted: 7 Mar 2014
Age class: Adult
Age: > 17

Meet Ferdinand, a beautiful white-fluked whale named by the Aquanauts Club of Sandy High School in 2014. Ferdinand is the first whale we have records of seeing in both Banderas Bay and Nicaragua, so we know this whale gets around! In Mexico, Ferdinand was first photographed in Banderas Bay on Valentine's Day 2003 and was seen in Banderas Bay again in December 28, 2008 with another adult whale. In December 2014, we learned from Cascadia Research Collective that Ferdinand was first photographed in 1997 in Nicaragua, making this whale more than 17 years old. Ferdinand has also been seen in Half Moon Bay and near the Farallon Islands in California.

Nickname: Panfilo
Patron: Juan Carlos Solís Onofre & Cristofer Suestegui Reyes
Gender: Unknown
First sighted: 31 Jan 2014
Age class: Adult
Age: Unknown

Humpback whale WGRP009, nicknamed Panfilo, has an exceptionally pretty fluke that is easy to spot with its classic black and white markings and raised edge on one side. We spotted Panfilo on the surface with two other whales on January 31, 2014 being very active. This is what is known as a courtship group, as the group was either 3 males beginning to compete for a female that was not present, or two males competing for a female that was present with them during that time. Courtship groups are exciting to observe, as you get to see fins, flukes, lots of blows, and body parts as the whales twist and writhe on the surface.

Nickname: Witold
Patron: The Niedzialkowski family
Gender: Unknown
First sighted: 23 Jan 2014
Age class: Adult
Age: Unknown

Beautiful humpback whale WGRP004, known as Witold, was seen traveling slowly south along "turtle beach," a 20-mile long stretch of deserted beach in our region where four species of sea turtles come to nest. Just after we photographed its fluke, Witold began to fin slap, tail lob, and breach. We are not sure yet whether this group of whales associates with the subgroup of north Pacific humpback whales that travel to Costa Rica, or if it was headed elsewhere. How humpback whales travel through these parts, where they rest, mate, court, calve, and sing are the big mysteries we are trying to solve. We hope to see Witold again next winter and will be looking for its fluke in catalogs of our colleagues in Oaxaca, Banderas Bay, and Washington in the meantime.

Nickname: JoJo
Patron: Jo Sharon
Gender: Female
First sighted: 19 Mar 2014
Age class: Adult
Age: > 8

JoJo, humpback whale WGRP024, is one of the last whales we were able to photo ID at the end of our first season on the water. JoJo has been seen before by researchers from Cascadia Research Collective, and we were able to identify it by searching for that tiny little white dot in the center of its tail to find a match between our two catalogs. Because of this match we now know that JoJo is a big fan of California, having been seen there in March, April, May, July, August, September, and October! JoJo has been seen 17 times around Monterey Bay and once in the Gulf of the Farallones; the first sighting was in 2006, and he/she was seen again in 2009, 2010, 2012, and 2013.

Nickname: Marlie
Patron: Kristian & Meghan Ruggiero
Gender: Female
First sighted: 19 Mar 2014
Age class: Adult
Age: > 15

Marlie, humpback whale WGRP025, is the last whale we photo ID'd during our pilot season in 2014. She was a mother, traveling north with her calf, most likely to California's Monterey Bay and Gulf of the Farallones, but possibly to Baja, the Channel Islands, or far north to Oregon or Washington. In late 2014 we found a match for Marlie's fluke in the catalog of Cascadia Research Collective, and learned that this whale had been seen 6 times before we photographed her in Mexico. Five of those sightings were around Monterey Bay, and one was in the Gulf of the Farallones. The first time this whale was seen was in 1999, and she was seen again in 2000, 2006, and 2009, telling us that she is at least 15 years old. Hopefully she and her calf survived the long journey north!
