In near-ground short-range navigation, it is thought that the velocity of image patterns (optic flow) over the retina ( 2) enables birds to compensate for lateral gusts ( 3). Over long ranges, birds compensate for crosswinds by fusing visual, olfactory, auditory, magnetic, and vestibular cues ( 1). When maneuvering toward a goal-such as during treetop landings-birds sense gusts and compensate. The way lovebirds glean wind orientation may thus inform minimal control algorithms that enable aerial robots to maneuver in similar windy and dark environments.

Our scaling analysis shows how this minimal sensorimotor solution scales favorably for bigger birds, offering local wind angle feedback within a wingbeat. Apparently, the visual horizon can be replaced by a gravitational horizon to inform the observed horizontal gust compensation maneuvers in the dark. This head stabilization enables the vestibular system to sense the direction of gravity.

The neck muscles not only stabilize the lovebirdsвЂ™ visual and inertial head orientations by compensating low-frequency body maneuvers, but also attenuate faster 3D wingbeat-induced perturbations. Our corroborated model for proportional yaw reorientation and speed control shows how lovebirds can compensate for lateral gusts informed by muscle proprioceptive cues from neck twist. To accomplish this feat, lovebirds primarily yaw their bodies into the gust while fixating their head on the goal using neck angles of up to 30В°. Despite being diurnal and raised in captivity, the birds fly to their goal perch with only a dim point light source as a beacon, showing that they do not need optic flow or a visual horizon to maneuver. We found that lovebirds can maneuver through 45В° lateral gusts similarly well in forest-, lake-, and cave-like visual environments. What information birds use to sense gusts and how they compensate is largely unknown. So basically the game wasn't even finished when it got launched, but you can't entirely blame Strife for this, he is the only one working on the game full-time and honestly I'm still impressed that he managed to make this game with a mere 25-30k dollar kickstarter, especially if you take the time and research to realize how in-depth this game actually is from Story to Gameplay, heck this game is already larger than most of it's kind.ДЄlso why are you complaining about extra content anyways.Flying birds maneuver effectively through lateral gusts, even when gust speeds are as high as flight speeds. (Also Strife actually dislikes when people use outdated versions of those characters, most because this will give people the wrong idea about hpw these characters work) The cheat engine versions of Spade and Torque are outdated, unbalanced, glitchy and incomplete. The reason Spade and Torque wasn't added into the game at launch was because of time restraints, by the time the game was launch the game was already delayed several time and alot of other content was either postponed or scrapped this include a massive majority of cutscenes, hub worlds, alternate costumes, Milla's adventure mode (Which will come with Spade and Torque's Classic Mode btw) and Rage Ravine. Spade debuted before Carol, so technecally Spade was actually the second character to be added into the game Spade and Torque was stretch goals for the game's kickstarter.
