I decided to salvage one of Disgustedorite's scrapped ideas. Unfortunately, it was somewhat difficult to make it interesting, and it did seem Earthclone-like, as a blend of a swift or swallow and a cowbird.

Hejahaida ((Pengsongalong sepisfaucium) (??? hedge-throat)
Creator: Coolsteph (Art by: Disgustedorite)
Size: 25 cm tall
Habitat: Koseman Temperate Woodland, Koseman Temperate rainforest, Vivus Lowboreal, Central Koseman Lowboreal, Vivus Prairie (uncommon; hunting only)
Diet: Carnivore (Gushitos, Sapworms, Leaping Soriparasite, Bludbug, Minikruggs, Mikuks, Feluks, Cloudswarmers, Soricinus)
Support: Endoskeleton (Bone)
Respiration: Active (Lungs)
Thermoregulation: Endotherm (Downy Feathers)
Reproduction: Sexual (Male and Female, Hard-Shelled Eggs in Woven Nests)
==Nesting and Aggregations==
Hejahaidas nest in woodlands, clearings, or other semi-open habitats. They nest in blackflora trees of smaller species or not fully-grown individuals, and camouflage the nest using leaves and its black down feathers. Lacking a gripping hind toe, it actually can’t grip tree branches as well as a songbird, and so prefers fairly thick branches. While Hejahaidas spend most of their time in woodlands, they may make forays into the surrounding plains to hunt.
Hejahaidas live in the densest flocks during the breeding season of Sapworms and Dartirs in summer, as well as the breeding seasons of Gushitos. Populations in the Lowboreal move north in autumn, seeking more food, although they do not migrate significant distances.
==Diet & Digestive Physiology==
While not as generalistic as its ancestor, it is nonetheless adaptable to a wide range of prey and nesting habitats, so long as the prey can be caught on the wing or gleaned from conspicuous elevated locations like branches. Due to its long-legged, heavy body, it is not so maneuverable as, say, a swift, limiting sharp turns. Consequently, it favors less-maneuverable or less-aware prey species. In accordance with its niche of catching prey on the wing, its jaws can open wide: even the tip of its upper jaw is surprisingly flexible.
Typically, it swallows prey whole, where it is immobilized in sticky saliva, pushed down into an esophagus outpocket, and further trapped behind “hedges” of backward-facing conical papillae at the base of the Hejahaida’s tongue. However, it may chomp down once on fairly fragile large prey. At times, it flies just above its prey to snatch it up in one downward gulp.
Much as for Earth’s swifts, its thick saliva glues together its many small prey into a ball of corpses in its “crop”, an out pocket of its esophagus just above its stomach. It regurgitates this ball to feed its young. As it tends to swallow prey whole, a few species, such as Gushitos, have sufficient adaptations against suffocation or crushing to still be alive when it returns to the nest, twitching futilely in a mass of prey.
It rarely eats fully-grown Dartirs, as even the smaller species are absurdly long relative to its body size and a hassle to bite apart. Juvenile Hejahaidas may try to hunt fully-grown Dartirs anyway, only to rip Dartirs’ back halves off with a midair chomp and seem confused or disappointed when their prey just keeps flying away. (The prey is doomed, of course, but it’s not entirely in their stomachs.)
==Other Feeding Behavior==
Hejahaidas forage in small flocks, seeking out large aggregations of their preferred prey. This often means following large herbivorous fauna as they inadvertently flush prey out of hiding, attract detritivores with their dung, pellets, or simply lure in bloodsucking pests.
It occasionally scrabbles onto large herbivorous fauna and launches itself when it spots prey. For some large fauna, its claws hurt.
==Ecology==
It has the same predators as its ancestor where their habitats overlap with that of its ancestor’s predators, such as the Woodsalcon.
Near bodies of water (especially permanent ones), they compete somewhat with Sruglettes, which have a similar diet. They associate more strongly with large herbivores near bodies of water, as a form of niche partitioning.
