Showing 6 of 6 situations

Situation 01Identification practice

A smaller goose, or a more distant goose?

You are watching two white geese through binoculars at a field edge. One looks smaller, but it is farther away; its bill is partly turned from you, and a photograph makes both birds appear equally close.

VISUAL EVIDENCE

Two views with different viewing depth

Fictional teaching schematic · symbols show evidence, not reliable species anatomy, a photograph or a real parcel map.

Two views with different viewing depthAbstract markers stand for the two observed geese. One is nearer; the other is farther and partly turned. Marker shapes do not depict identification features.Nearer viewFarther viewViewpointTurned / partial viewUnequal viewing depth

The near and far markers describe the scenario’s views, not a calibrated size or distance comparison.

Supplied by this situation

  • Two white geese are observed from one viewpoint.
  • The scenario supplies unequal viewing depth and a partly turned bill view.

Not supplied by this view

  • Comparable head and bill views for both individuals.
  • A measured, common-scale body-size comparison.
What should you record before deciding between Snow Goose and Ross’s Goose?

Choose the next step

Read the answer and explanations

Best next stepWait for comparable views and record several visible features.

Why each choice matters

  1. Use the apparent size difference as the deciding feature.

    Different distances and posture change apparent size. This comparison does not establish the smaller-looking bird’s species.

  2. Wait for comparable views and record several visible features.

    A clearer bill and head profile, considered together with body proportions, supplies evidence that this view currently lacks.

  3. Use the nearest bird’s identification for both birds.

    Association is useful context, but one identified bird does not establish another individual’s identity.

direct observation

What was actually seen, heard or measured, with the view and context recorded.

Common mix-up: A sound can be observed without confirming an animal’s identity or number.

inference

An explanation or estimate drawn from observations, rather than another separately observed fact.

Common mix-up: A confident file name, habitat label or repeated copy does not add a new observation.

sample coverage

The view or ground, and observation interval, that were actually checked for a particular record.

Common mix-up: Hidden or uninspected ground lies outside that checked sample, even when it is nearby.

Situation 02Identification practice

Can a reference photo fill the gaps?

Your cropped photograph shows a brown duck’s head and part of its flank, with glare obscuring the bill. At home, you compare reference views of female Mallard, Northern Pintail and American Wigeon, but their angles differ and a companion adjusts the photograph’s colour to resemble one reference.

VISUAL EVIDENCE

A cropped view beside separate reference views

Fictional teaching schematic · symbols show evidence, not reliable species anatomy, a photograph or a real parcel map.

A cropped view beside separate reference viewsA conceptual image frame contains labelled evidence tiles for the head and partial flank. A patterned tile marks bill glare; a dashed area lies outside the crop. Separate cards represent references.Current cropped frameHeadvisiblePartialflankBill glareOutsideframeReference views123

These are evidence tiles, not a reconstructed duck. Reference cards do not add pixels to the cropped view.

Supplied by this situation

  • The current photograph includes the head and part of the flank.
  • The references use different viewing angles.

Not supplied by this view

  • The bill detail obscured by glare.
  • The body and wing evidence outside the original crop.
Which comparison adds useful evidence without inventing features?

Choose the next step

Read the answer and explanations

Best next stepCompare visible structures at suitable angles and leave the missing features unresolved.

Why each choice matters

  1. Choose the reference whose overall brown colour matches the edited photograph.

    Editing changes the comparison itself; a close colour match does not reveal the obscured bill or distinguish the missing structures.

  2. Use the reference bird’s wing pattern to complete the cropped observation.

    A reference shows that photographed bird, not the unseen parts of yours. Completing the image this way turns an example into invented evidence.

  3. Compare visible structures at suitable angles and leave the missing features unresolved.

    A structured comparison can show what remains possible while a clearer view of the same individual is still needed.

Situation 03Identification practice

One photograph, two conflicting records

Your deer photograph clearly shows the ears, while brush conceals the rump and tail, so your notebook records an uncertain species. Later, a companion renames the shared file “Mule Deer” and creates a confidently labelled map pin without obtaining another view.

VISUAL EVIDENCE

One photograph, two labels derived from it

Fictional teaching schematic · symbols show evidence, not reliable species anatomy, a photograph or a real parcel map.

One photograph, two labels derived from itA source-frame card marks the ear view and hidden rump or tail. Two arrows lead from that same frame to a file-name card and a map-label card, each carrying the name Mule Deer.One source photographEar viewRump / tail hiddenFile nameMule DeerMap labelMule Deer

The arrows show the origin of two labels. They do not represent two additional animal observations.

Supplied by this situation

  • The source photograph shows ears.
  • The same image was given a file name and a map label.

Not supplied by this view

  • A view of the concealed rump and tail.
  • A new observation accompanying the renamed file or pin.
How should the shared records be reconciled?

Choose the next step

Read the answer and explanations

Best next stepKeep the visible-feature record and make the uncertainty explicit on the shared file and pin.

Why each choice matters

  1. Keep the visible-feature record and make the uncertainty explicit on the shared file and pin.

    The renamed file adds a claim, not new evidence. Consistent uncertainty prevents later readers from mistaking a label for an additional observation.

  2. Accept the species because the file and pin now agree.

    Both labels came from the same unsupported decision; repeating it in two places does not supply the hidden tail or rump.

  3. Keep the confident public pin but note uncertainty only in your private diary.

    That leaves others with a stronger claim than the evidence supports, and the private correction may not travel with the shared record.

Situation 04Identification practice

What does your GPS pin locate?

You watch a deer across a field from a permitted observation point and save a phone location. At home, the pin lands beside the road where you stood, while your memory places the animal near a distant shelterbelt.

VISUAL EVIDENCE

A phone fix and a separate estimated area

Fictional teaching schematic · symbols show evidence, not reliable species anatomy, a photograph or a real parcel map.

A phone fix and a separate estimated areaA conceptual plan shows an observer and phone fix on one side, with a dashed animal-location estimate near a landmark on the other. A dotted line represents the viewing relation without a scale.Sight lineObserverPhone fixEstimated animal areaLandmark

No coordinates, measured separation, parcel boundary or route are supplied by this drawing.

Supplied by this situation

  • The phone saved the place where the observer stood.
  • The animal was described relative to a different landmark.

Not supplied by this view

  • A phone measurement made at the animal’s position.
  • A confirmed parcel assignment or accuracy for the estimated animal area.
How should the map notebook distinguish these two locations?

Choose the next step

Read the answer and explanations

Best next stepKeep the observer fix and add a separate estimated animal location.

Why each choice matters

  1. Move the saved GPS pin to the shelterbelt and retain the same accuracy.

    The phone measured your position, not the animal’s. Moving the pin without changing its status gives an estimate false precision.

  2. Keep the observer fix and add a separate estimated animal location.

    Separate records preserve what was measured and what was inferred; direction, landmarks and uncertainty make the estimate interpretable later.

  3. Use the observer pin as evidence the deer occupied that parcel.

    A pin at your feet does not locate an animal across a boundary, even when the sighting itself is reliable.

observer fix

The recorded position of the observer’s device when its location was saved.

Common mix-up: It locates the observer, not automatically the animal seen across the field.

estimated animal position

An approximate animal location inferred from the view, direction and landmarks, kept separately from the observer fix.

Common mix-up: Moving a phone fix does not preserve its measured status or turn the animal estimate into a measurement.

Situation 05Identification practice

A large animal at the timber edge

Through a gap in the trees, you see the shoulder and part of the head of a large cervid. The legs and full profile remain hidden, and a companion points out that the surrounding habitat appears suitable for Moose.

VISUAL EVIDENCE

A narrow viewing window and missing evidence

Fictional teaching schematic · symbols show evidence, not reliable species anatomy, a photograph or a real parcel map.

A narrow viewing window and missing evidenceAn abstract window marks the shoulder and partial-head evidence named in the scenario. Patterned areas mark unavailable legs and full profile. Neutral Elk and Moose cards remain separate.Viewing gapShoulder / partialheadLegs unavailableFull profileunavailableElk ?Moose ?

The coloured blocks are evidence placeholders. They are not silhouettes or morphological comparisons of Elk and Moose.

Supplied by this situation

  • The scenario supplies a shoulder and part of a head through a gap.
  • A companion offers a habitat-based suggestion.

Not supplied by this view

  • The legs and unobstructed full profile.
  • A complete, linked set of individual identification views.
What is the strongest response to an uncertain Elk-or-Moose identification?

Choose the next step

Read the answer and explanations

Best next stepContinue observing from the known position and document the missing features.

Why each choice matters

  1. Treat suitable habitat as the deciding identification feature.

    Habitat can guide observation, but it neither proves which species is present nor replaces features of the actual animal.

  2. Use the largest-looking visible body part to settle the question.

    An incomplete view offers no dependable whole-body comparison; distance, posture and cover can distort that impression.

  3. Continue observing from the known position and document the missing features.

    An unobstructed body and head profile may resolve the uncertainty without pretending the present view already does.

Situation 06Identification practice

One flock, several individual identities

You follow a clearly identified duck approaching a wetland with several less distinct birds. They cross behind vegetation and emerge in a different order, so you can no longer tell which individual you were tracking.

VISUAL EVIDENCE

Continuity before and after hidden movement

Fictional teaching schematic · symbols show evidence, not reliable species anatomy, a photograph or a real parcel map.

Continuity before and after hidden movementThe first view uses A, B and C as subject markers, with A singled out as the earlier observed individual. A patterned cover band separates a new view labelled 1, 2 and 3. Dotted branches show unresolved continuity.Before coverNew view?ABC123Earlier observed individualView lost in coverContinuity unknown

Letters and numbers are diagram labels, not permanent animal tags or a flock count. The drawing does not match any new-view bird to A.

Supplied by this situation

  • An earlier individual had a clear identification view.
  • The group reappears in a different order after cover.

Not supplied by this view

  • Continuous tracking through the hidden part of the view.
  • A confirmed match between A and any numbered bird in the new view.
What should happen to the identification after that loss of continuity?

Choose the next step

Read the answer and explanations

Best next stepRe-establish the identity of each bird you need to assess.

Why each choice matters

  1. Re-establish the identity of each bird you need to assess.

    The earlier identification belongs to a particular observed individual. Losing that connection means the new view needs its own evidence.

  2. Transfer the identification to the bird now leading the group.

    Position in a flock can change, so order alone does not reconnect the present bird with the earlier observation.

  3. Give every bird the identity of the one you identified well.

    Mixed or uncertain groups require individual assessment; a clear view of one does not supply hidden features for its neighbours.
