Silky sifaka (Propithecus candidus) are among the worlds most endangered primates, with less than 1000 remaining in the wild. Native to the steep, mountainous rainforests of northeastern Madagascar, silkies, as they are often called, make ‘zzuss’ vocializations. Sounding like a combination of a sneeze, a lip smack, and sifaka, these calls act as both alarm…

Field Frame Friday: Karma Karma Chameleon
Many chameleons (especially of genus Furcifer) can change color extremely rapidly not only for camouflage, but also for communication, courtship, and contests. A recent study finds that complex and quick color changes are attributed to two layers of skin that contain crystals that reflect light. The double layer of skin also may provide thermal protection…
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.

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: 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 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: 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: World Lemur Festival!!
Although they may not look much like their more famous dancing sifaka cousins, woolly lemurs (Avahi) move by vertical clinging and leaping. Eastern woolly lemurs (Avahi laniger) like the one seen here are nocturnal, pair-living, folivorous (leaf-eating) primates only found in Madagascar. Madagascars’ 112 and counting lemur species are currently the most threatened mammal group…
Field Frame Friday: Chameleon coloration
While many people think that chameleon coloration serves only as camouflage, chameleons also change color to communicate with other chameleons. These color changes maximize communication between chameleons while minimizing the change of predation. [Photo and caption by Meredith Lutz] Reference Stuart-Fox, D., & Moussalli, A. (2008). Selection for social signalling drives the evolution of chameleon…
