Intelligence in Corvids and Apes: a Case of Convergent Evolution? Amanda Seed*, Nathan Emery & Nicola Claytonà

For comparative proximate analyses we empha- size the need to be explicit about the level of analysis to reveal the type of convergence that has taken place. Although there is evidence that corvids and apes solve social and physical problems with similar speed and flexibility, there is a great deal more to be learned about the repre- sentations and algorithms underpinning these computations in both groups. -
Florida Scrub-Jays
SCIENCE in the SCRUB At Home in the Florida Scrub Archbold Biological Station LENGTH Module 1: Florida Scrub-Jays: 1 hour prep 20 minute video At Home in the Florida Scrub 30 minute activity By the Archbold Biological Station Education Department, 2014 with support from the Southwest Florida Water Management District MATERIALS At a Glance In this lesson, students learn how Florida Scrub-Jays have adapted to survive in the Video Florida scrub ecosystem, and how scientists use banding and long-term research to Jay Family jpeg understand and protect this endangered species. Students watch a video, then Printouts work in pairs to identify parts of the Florida Scrub-Jay’s family life. Tape or Glue Pens or pencils Directions 1. Watch “At Home in the Florida Scrub” video. 2. Review concepts from video with questions about Scrub-Jay habits, cooperative breeding, and the graph shown in the video. Questions supplied on next page. KEY VOCABULARY 3. Divide students into pairs for The Bird Search Story narrative game. Dense Oak Scrub Learning Goals Ecosystems • Florida Scrub-Jays have very specific needs and require scrub habitat. Empirical • Some animals, such as Florida Scrub-Jays, live in family groups, headed by a Food Chains breeding pair, with members that help each other. This adaptation of behavior Habitat is called cooperative breeding and has specific advantages. Interdependence • Cooperative breeding evolved in scrub-jays because: 1) scrub habitat and Scrub Habitat resources were limited, forcing scrub-jays to cooperate 2) individual scrub-jays Thicket benefited from helping their siblings so were more successful when raising their own young (experience matters) and 3) scrub-jay families were stronger when siblings helped and more young birds survived. -

Nine fossil premaxillae and mandibles of the Florida Scrub-Jay(Aphelocoma coerulescens)are reported from a late Pliocene sinkhole deposit at Inglis 1A, Citrus County, Florida. Vertebrate biochronologyplaces the site within the latestPliocene (2.0 to 1.6 million yearsago, Ma) and more specificallyat 2.0 l-l .87 Ma. The fossilsare similar in morphology to living Florida Scrub-Jaysin showing a relatively shorter and broader bill compared to western species,a presumed derived characterfor the Florida species.The recent elevation of the Florida Scrub-Jayto speciesrank is supported by these fossils by documenting the antiquity of the speciesand its distinct bill morphology in Florida.

Florida Scrub-Jay Game
Around the Bend Nature Tours Field Study Florida Scrub‐Jay Game An Adaptation of Project WILD’s “How Many Bears Can Live in this Forest?” And the “Osprey Game” created by the Staff at Pelotes Island Nature Preserve, Jacksonville, Florida http://pelotes.jea.com/ Grade Level: 4th – 12th Grades Subject: Science Duration: 35 Minutes Materials: One set of Food Cards*, 21 Fledgling Cards, Optional: 7 nest markers (sturdy leaves) NGSSS: SC.3.N.1.1, SC.3.N.1.6, SC.4.L.17.2, SC.4.L.17.3, SC.4.L.17.4, SC.5.L.15.1, SC.5.L.17.1, SC.7.L.17.1, SC.7.L.17.2, SC.7.L.17.3, SC.912.L.17.6 C, SC.912.L.17.20 Overview: In this role-playing game, students become scrub jays and compete with man for their living space, see the effects of habitat loss, and deal with other natural obstacles. The purpose of this game is to give the players a better understanding and appreciation for the life and struggles of this unique and rare bird. Objectives: Students will discover how the Florida scrub jay lives in extended family units. Students will learn that the scrub jay diet consists mainly of acorns, but they are omnivorous birds. Students will understand that habitat restoration is critical to the survival of the scrub jay species. Background: See attached Florida Scrub Jay fact sheet. SETTING UP THE GAME: 1. Assemble the students in “Family Groups” of scrub jays. Each family group will have 2 adults (a mated pair) and 1-3 sub-adults. -

Metapopulation Dynamics and Landscape Ecology of the Florida Scrub-Jay, Aphelocoma Coerulescens
METAPOPULATION DYNAMICS AND LANDSCAPE ECOLOGY OF THE FLORIDA SCRUB-JAY, APHELOCOMA COERULESCENS By BRADLEY M. STITH A DISSERTATION PRESENTED TO THE GRADUATE SCHOOL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF FLORIDA 1999 Dedicated to my wife and best friend, Ellen Mary Thorns ACKNOWLEDGMENTS I wish to acknowledge each of my committee members for their unique contributions to this dissertation. My chairman, Dr. Stephen R. Humphrey, stimulated my interests in issues relating to philosophy, policy, and management. His broad interests and ability to take on multiple careers were remarkable. In my times of need he provided unfailing support while allowing me great freedom to pursue my own course of study. As director of Archbold Biological Station, co-chairman Dr. John W. Fitzpatrick provided me with a wonderful opportunity to study the Florida Scrub-Jay at this world-class research facility. His ability to perform brilliantly as director, researcher, and conservationist is inspirational. I am grateful to him for sending a generous U.S.F.W.S. grant my way to support me towards the end of my program. I was also privileged to work under the tutelage of the legendary pioneer of Florida Scrub-Jay research, Dr. Glen E. Woolfenden, who showed me the world from a Florida Scrub-Jay's perspective. My collaborative research with Dr. Lyn Branch on the Vizcacha and the Florida scrub lizard, was a joy. She forced me to think about landscape ecology and the metapopulation dynamics of "lesser" organisms. Her support, financial and otherwise, was extraordinary, and a nicer person I have never met. -

Crows, Ravens, and Jays
Crows, Ravens & Jays Order Passeriformes Family Corvidae Members of the corvidae family are not known for their sublety or shyness. Crows and jays are noisy, boisterous, tolerant of humans, and smart. Because of their intelligence they are quick to find new food sources, like a backyard feeder. When they do, they can overwhelm the area and drive other birds away. Ravens are much more wild and prefer Pennsylvania’s remote wilderness areas. The birds are physically adapted for a variety of habitats and flight pat- terns - crows and ravens spend a great deal of time in the air. Their bills and feet are well-suit- ed to both prey on small animals or eat a wide variety of plant materials from fruits and berries to seeds or even larger acorns. Blue Jay Cyanocitta cristata Blue Jays are considerably bigger than a robin, at almost a foot in length from the tip of their prominent head crest to the tip of their tail. Their blue bodies are boldly marked with black and white. Their large straight bill is a tool for grabbing food and hammering at it before eating. They can eas- ily hold an acorn in their feet and chisel into it with their bill. Preferred jay habitats are woodlands, partly wooded suburbs, farms or even city lots - as long as they can find food. Jays are true omnivores, though most of their diet comes from acorns, beechnuts, corn, grain, fruits and berries. They will eat carrion when they find it. All kinds of insects and small animals make up the remainder of their diet: ants, caterpillars, beetles, grasshoppers, spiders, snails, frogs, small rodents, and even the eggs and nestlings of other birds. -
