White-headed Marsh Tyrant (Arundinicola leucocephala)

…a small species of tyrant flycatcher (Tyrannidae) that is the sole member of the genus Arundinicola. White-headed marsh tyrants breed in tropical South America, ranging from Colombia, Venezuela and Trinidad south to Bolivia, Argentina and Paraguay. True to their common names white-headed marsh tyrants typically inhabit marshy savannas, reedbeds, and the edges of mangrove swamps. Like other flycatchers they feed almost exclusively on insects which are caught in typical flycatcher fashion

Every time I go downstairs to the laundry room, this pigeon tries to seduce me.

"we have incompatible genitals" is now my favorite excuse.

Even the pigeons want to attack you in Australia.

Red-ruffed Lemur (Varecia rubra)

…an endangered species of lemur (Lemuridae) which, like all lemurs, is native to the island of Madagascar, where it is restricted to the rainforests of Masoala Peninsula. Red-ruffed lemurs usually live in small groups (sometimes larger groups are seen) which are lead by females. Like other lemurs, red-ruffed lemurs are mainly frugivores (fruit eaters) and typically seen foraging high in the canopies of trees. 

Currently red-ruffed lemurs are listed as endangered as they face threats from habitat loss due to their need for tall primary forests. Hunting remains a threat to their survival as well.

Small-headed Flies (Family: Acroceridae)

Also known as spider or hunchback-flies. Acroceridae is a family of Nemestrinoid flies which boast a cosmopolitan distribution, but interestingly are not abundant anywhere throughout their range. There are ~550 species of acrocerids described which are housed in 3 subfamilies, many but not all of them are bee or wasp mimics. Acrocerids are parasitoids of spiders, their first-instar larvae will seek out and force themselves inside the spider where they usually lodge themselves near the book lungs. They will then complete the rest of their development inside the spider, and when they are ready to hatch they will exit the spider killing it in the process. Adult small-headed flies are more tame compared to their young as they feed on nectar, using a long proboscis which is tucked under their body.
