Wildlife, Animal Biology and Animal Behavior

In wildlife photography, insight into biology of animals, their preferences and their behavior is of significant importance.

Special Topics

Species in Focus:

I created podcasts about a selection of species. In each episode, you’ll learn more about a particular species—from its biology and behavior to its distribution and ecological role.

Snapshots:

Wildlife States & Transitions

The table below divides the year into practical windows for planning time outdoors — each phase links animal activity, habitat change, and how easily species can be found and photographed.

Phase Period Field Signals
The Opening Mar 20 - Apr 20 Ice retreats; open water expands; early migrants arrive; mammals re-emerge
The Waking Apr 20 - May 20 Leaf-out begins; rapid species variety rises; insects emerge
The Rush May 20 - Jul 10 Nesting peaks; young dependent; feeding rates high
The Hidden Jul 10 - Aug 20 Closed canopy; dense cover; insect peak; visibility sharply reduced
The Departure Aug 20 - Oct 20 Migration pulses; staging flocks; mixed species groups
The Fading Oct 20 - Dec 15 Late migrants pass; freeze-up begins; northern visitors appear
The Silence Dec 15 - Mar 20 Low activity; tracks reveal presence; resident species dominate

Phases and dates reflect the Montréal region (southern Québec). Adjust for latitude, elevation, and year-to-year weather.

Animal Behavior and Functions

Animal behaviours can be classified by observable actions and their functional context across species — from birds to mammals and beyond. The list below outlines these behaviours and their possible functions. You can also explore them interactively: MUUUH Animal Behavior Videos

All content on this page — including photos, videos, and field audio recordings — was created by Karl-Heinz Müller, a Montréal-based wildlife filmmaker, sound recordist, and photographer. Founder of MUUUH and Québec Sauvage, he has spent over a decade documenting Canada’s natural habitats through immersive soundscapes and wildlife films. Learn more about Karl-Heinz
