 **Wild-Caught Concerns: **Wild specimens may carry parasites (ticks, internal worms) and often arrive stressed. They also tend to be more nervous. It is highly recommended to seek **captive-bred (CB)** individuals both for ease of acclimation and to avoid depleting wild populations. Captive-bred Baroni are typically calmer and more accustomed to human presence. Supporting responsible breeders helps reduce demand for wild collection. **Wild-Caught Concerns: **Wild specimens may carry parasites (ticks, internal worms) and often arrive stressed.

 + 
 +=== Habitat: ===

 +Subtropical dry forests and savannas. Baron's Racer is primarily **arboreal to semi-arboreal**, living among the trees and bushes of **thorny scrub forests**, **savannah woodlands**, and **subtropical dry forests** ((

 +)). It can also be found in tropical to subtropical **gallery forests** (forests along waterways) and transitional areas between woodland and grassland. Microhabitat usage centers on **trees**, **shrubs**, and **vines **a few meters off the ground. They often hide amongst foliage, in vine tangles, or under bark and tree hollows. Baroni have been observed resting on branches and **“flying” between limbs** (leaping from branch to branch) in pursuit of prey ((

 +=== Elevation: === 
 + 
 +Most records are from **low elevations** (100–500 m above sea level) in flat or gently rolling terrain of the Chaco and adjacent plains. In the Andean foothills (e.g. Salta province) they may occur up to around ~1,000 m, but they primarily favor lowland habitats.

 +=== Microhabits: === 
 + 
 +//Philodryas baroni// is **arboreal**, but not strictly canopy-bound. Individuals are often encountered in **small trees and shrubs** a few feet off the ground ((

 +)). They do not typically burrow, but may use rodent burrows or hide under logs/leaf litter for shelter or thermal regulation, especially during cooler weather or at night. In captivity, they appreciate both climbing opportunities and some ground cover or a hide for security.
