Not really. I would suggest these were highly arboreal, possibly canopy dwellers given the big hallux claw, long hands with big manual claws, herbivorous diet. The only morphometric analysis I know of that tested their lifestyle was Bell & Chiappe 2007 which found them to plot among aerial foragers like Buteo, which seems odd for an herbivore but maybe it was soaring around looking for fruit and seeds or something (unless this is an artifact of long, high aspect ratio wings that were used more for gliding long distances). The feathering is based somewhat on birds of prey that forage out in open fields.
Wow, gorgeous. Love the colors and the "long" feathers on the legs look natural and believable. (Surely I can't be the only one a little annoyed at every long feather anywhere on the leg of a paravian or avialan being referred to as a "wing". Pennaceous leg feathers do not a wing make. Just ask hawks, ptarmigans, or any number of thousands of extant birds with long "trousers" that are definitely not using them for anything flight-related.)
Thanks! Though at least in this case there are clear feathers on the tarsus (in contrast to the other so-called "hind winged" species in the new paper, like Confuciusornis, which appear to have utterly normal length if not rather short feathers on the tibia only). The very long tibia feathers in this guy combined with the absolutely huge talons are especially hawk-like.
