Sunday Sketch: Child Labor

Like almost all activities in a social insect colony, nest building involves team work. Weaver ants, Camponotus (Myrmobrachys) senex, build elaborate nests made of stitched together leaves that are subdivided into small interconnected chambers. The work of tying these leaves together involves a surprising joint effort by both adults workers and larvae. Adult workers will carry individual…

Field Frame Friday: Sneaky Snake Alert!

Many animals may respond to the presence of a predator by eliciting a signal that alerts other individuals in the area. Since snakes are a major predator of monkeys, they often respond very strongly whenever one is nearby. The female long-tailed macaque (Macaca fascicularis) in this photo is very upset with a large boa constrictor…

Creature Feature: the Greater Spear-Nosed Bat

“I think he’s in the termite mound!” I shouted. Camila Calderón, a researcher at the Max Planck Institute of Animal Behavior, called back: “No! Let’s keep looking over this hill! Maybe the signal is bouncing!” Camila studies the greater spear-nosed bat, Phyllostomus hastatus (or just Phast to its friends). With a typical adult wingspan of…

Sunny Sketch: No Inkling of Ink

The dumbo octopus (genus Grimpoteuthis) is distinguished from its octopus brethren by its adorable ear-like fins that provide its namesake. However, there are also a few other characteristics that make this little creature unique. First of all, it is indeed a little creature compared to most other octopodes, with an average size of just 20-30…

Field Frame Friday: Happy Valentine's Day!

Titi monkeys are pair-bonding monkeys. They engage in affiliative behaviors like the one depicted here: tail twining! Titi monkeys tail twine during the day in order to maintain contact with their partner, similar to hand-holding in humans. At night, titi monkeys tail twine to maintain proximity and help each other balance while sleeping! Happy Valentine’s Day!…

NOAA researcher and marine mammal acoustician, Arial Brewer, shares her fascination with animal communication and love of the sea!

Field Fiasco Friday: Case of the Missing i-Pad

The animal I study (the kinkajou, Potos flavus) is arboreal and nocturnal. This means that to watch one, I have to run through the Panamanian rainforest at night. While looking up. To manage this, I rely a lot on technology. First, I put collars on my kinkajous that transmit a radio signal. I can use…

Publish and perish: A graduate student perspective

As I sit here writing this, I’m simultaneously observing the two fish swimming on my computer monitor. It is a Saturday, and like most graduate students, I have tried to master the art of multi-tasking. This weekend, however, I’m having a particularly hard time concentrating on my research. This is not because I am jaded…

Sunday Sketch: Birds of a feather

For most raptors, hunting is not a team sport. Harris’ hawks, however, play the game a bit differently. Although a few other raptors are known to hunt cooperatively, Harris’ hawks are by far the most cooperative and coordinated in their hunting behavior. They use many strategies for hunting that rely on coordinated maneuvers by each…

Field Frame Friday: There is no hiding from me, EYE see you!

Jumping spiders (phylogenetic family: Salticidae) of all arthropods (i.e. invertebrates with an exoskeleton)! In addition to the 2 sets of eyes seen in this photo, jumping spiders also have 2 sets of eyes on the top of their head. Each set has specialized function, from detecting changes in light, motion, and color, to the ability…

Field Frame Friday: A whole new meaning to being called a "bird-brain."

While the idiom, “bird brain” may mean a silly or stupid person, we may want to reconsider it as a compliment. Turns out, African grey parrots (Psittacus erithacus) have more abstract logic than the average human toddler. When briefly shown the contents inside two canisters (walnuts or nothing) and then presented the parrots with the…

Field Frame Friday: No provisioning allowed!

When humans voluntarily feed wildlife, it is referred to as provisioning. Although this may appear a harmless and fun activity for visiting tourists, these small acts of “kindness” can have profound effects on wildlife. For example, provisioning can lead to increased aggression among individuals monkeys in a social group, as they are competing over a…

Field Frame Friday: Day gecko, night gecko

Madagascar day geckos (Genus Phelsuma) are important pollinators for Malagasy plants. In fact, the plants often have colored nectar, which is preferred by the day geckos. [Photo and caption by Meredith Lutz] Minnaar, I. A., Köhler, A., Purchase, C., & Nicolson, S. W. (2013). Coloured and Toxic Nectar: Feeding Choices of the Madagascar Giant Day…

Field Notes: Jungle Prozac

Jungle Prozac, my mom calls it. A potent drug, elements unknown. Possible components include the slurry of plant-produced volatile compounds infusing the air, the pleasing fractal dimensions of so many trees, adventure-induced hormone cascades, frequent exercise, a vegetative buffer from the anxieties of society, and a palm-framed view of Lake Gatun, Panama. Whatever its true…

Field Frame Friday: Mistletoe Munching

Mistletoe does not only serve to incite smooches on Christmas, but it’s also a tasty snack for Diademed Sifakas (Propithecus diadema) in Madagascar. When resources are few and far between in the winter, Sifakas rely on mistletoe and this reliance can reduce group cohesion in fragmented forests. Mistletoe may bring humans together, but it makes…

Field Frame Friday Holiday Edition: Christmas in the Field

Alexander is spending Christmas on Barro Colorado Island in Panama, part of the Smithsonian Tropical Research Institute. The island is quiet for the holiday: only him, a handful of guardabosques (“Forest Guards”, similar to game wardens, that help maintain and protect the Barro Colorado National Monument), and a few cooks. They had a special lunch,…

Field Frame Friday: Beggars can’t be choosers

Ever had your pet beg to you for food? Well this is no different. This is Emma, performing her signature “hands out” behavior to indicate that she would like you to share whatever scrumptious things you have with her. Emma is a long tailed macaque that lives in a tourist park outside of Kuala Lumpur,…

Field Frame Friday: Literal love birds!

Madagascar love birds are the smallest lovebirds and one of three sexually dimorphic (meaning males and females look different in size or color) lovebirds. Lovebirds got their names as they often sit in pairs preening each other’s feathers [Photo and caption by Meredith Lutz] Dubuc, R. G. Family Tree of the African Love Bird. AFA Watchbird, 5(1),…

Field Notes: PhD Research or Arts-n-Crafts Hour… Why Not Both?

When you’re in the business of making nearly a thousand clay caterpillars by hand, there are a few must-have investments: Spotify premium (for hours’ worth of podcasts), ludicrous amounts of alcohol wipes (to scrub your stubbornly ink-dyed hands), more Copic marker refills than you think you would ever need (so you don’t have to drive…

Field Frame Friday: Excuse me? May I park my infant here please?

Ruffed lemurs, like the black and white ruffed lemur pictured here (Varecia variegata editorum) exhibit a unique infant rearing strategy among primates. They give birth to litters of 2-3 altricial (meaning that they are rather helpless and not as developed at birth) babies in a nest. The babies stay in the nest while one adult…

Field Frame Friday: Beware the hair!

It only takes one of these caterpillars to royally ruin a perfectly good field day. Caterpillars like these are covered in irritating hairs to avoid predation. However, if a human has an unexpected encounter with one, it can result in an uncomfortable skin rash that can last from minutes to hours. Thankfully I found this…

Field Frame Friday: Eat Dirt!

Geophagy, or eating soil, is observed in a variety of folivorous (leaf-eating) primates, including diademed sifaka (Propithecus diadema) in the Maromizaha Protected area. This behavior may help to protect against harmful chemicals found in the leaves that they consume. [Photo and caption by Meredith Lutz] Semel, B. P., Baden, A. L., Salisbury, R. L., McGee, E….

Field Frame Friday: PVC is marine mammal enrichment’s best friend.

This is what science looks like! That is if your science involves building enrichment puzzles for seals to help them learn how to forage for food! Enrichment and is a tool used to promote positive behaviors and provide cognitive stimulation to animals. This stimulus aims to encourage a species-typical “rock flipping” behavior in Hawaiian monk…

How to make friends at conferences: a crash course in academic networking

It would not be a very bold statement for me to say that “networking is important.” This is something most graduate students have likely heard from lots of different sources like their parents, their supervisors, or any formal professional development course they’ve taken. The reason this advice is so common is because it’s true. However, it can…

Field Notes: Breaking up (with your study species) is hard to do!

They say you never forget your first love, and I know that to be true…for birds. If you’re a regular reader of the Ethogram, you know that we put our hearts and souls into our study species. I’m often asked “Why that bird?” and while it’s easy to respond “Because they’re awesome!” there are actually…

Sunday Sketch: Speedy Beetles

Watch out! Tiger beetles run so fast that they temporarily go blind. To avoid tripping hazards (and find prey!) they run in short bursts, taking breaks to orient.

Field Notes: Singing Titi Monkeys

A typical morning of titi monkey vocalization recording starts off with a 4:30 AM alarm. I roll out of bed, start coffee, and am out in the door in under ten minutes. The 20-minute drive goes by quickly as I mechanically drink my coffee. As I gather my recorder, microphone, and camera, interns begin to show…

Field Frame Friday: Dimethylsulfoniopropionate: what a mouth full… of food.

Bluefin trevally (Caranx melampygus) or ‘omilu in Hawaiian are able to detect dimethylsulfoniopropionate (say that 5 times fast, or just say DMSP). DMSP is a chemical produced by phytoplankton (marine algae) that is an indicator of food productivity. This chemosensory adaptation is important for foraging success!

Sunday Sketch: Glow-In-The-Dark Pocket Shark

A new species of pocket shark (Mollisquama mississippiensis) that was found in the Gulf of Mexico has recently been classified. Pocket sharks get their name from the “pocket” glands behind their pectoral fins. The glands in glow-in-the-dark pocket sharks produce a bioluminescent fluid. Their bodies also generate light all over from bundles of glandular organs…

Creature Feature: Banggai cardinalfish

A population of small reef fish hiding amongst the spines of sea urchins in the Banggai Archipelago, doing their best to avoid capture by the hands of ornamental fish collectors, may now depend on their captors to ensure existence in the wild. The Banggai cardinalfish (Pterapogon kauderni) are in trouble as result of their unique…
