Focal length needed to frame it#
For a subject about 12 cm long filling a third or half of the frame width horizontally. Small birds demand long lenses and a close approach — a blind or feeder setup helps.
| Distance | ⅓ of frame (FF) | ½ of frame (FF) | ⅓ of frame (APS-C) | ⅓ of frame (MFT) |
|---|---|---|---|---|
| 5 m (16 ft) | 434 mm | 629 mm | 289 mm | 217 mm |
| 10 m (33 ft) | 868 mm | 1,259 mm | 579 mm | 434 mm |
| 15 m (49 ft) | 1,302 mm | 1,888 mm | 868 mm | 651 mm |
| 20 m (66 ft) | 1,736 mm | 2,517 mm | 1,157 mm | 868 mm |
| 30 m (98 ft) | 2,604 mm | 3,776 mm | 1,736 mm | 1,302 mm |
| 50 m (164 ft) | 4,340 mm | 6,294 mm | 2,893 mm | 2,170 mm |
About the Brown-headed Nuthatch#
The brown-headed nuthatch (Sitta pusilla) is a small songbird found in pine forests throughout the Southeastern United States. Genetic analyses indicated low differentiation between northern and southern populations in Florida. A population on the Bahamas showed moderate to high differentiation compared with Florida populations.

Field-craft tips#
- They work down trunks head-first — try a low angle looking up.
- Trunk-clinging birds sit in shade: watch your shutter speed and use zone AF to avoid focusing on bark.
- Sightings peak in January, February, March, April and May, which is when you'll have the most chances.
- Tiny subjects: get close with a hide or feeder perch rather than cropping heavily.
Ethics#
- The welfare of the animal comes first: if it changes its behaviour because of you, you are too close.
- Stay on trails, respect closures around nests, leks, dens and haul-outs.
- Avoid playback and baiting in sensitive seasons; never bait predators.
- Don't share precise locations of rare, nesting or roosting animals publicly.
