The Enrichment Budget and the Stereotypic Parrot
A shelter has a $400 monthly enrichment budget for 40 animals, including one African grey parrot, "Juno," surrendered four months ago. Juno has plucked her chest and leg feathers over the past two months and paces the perch bar repetitively for 20-30 minutes at opening and closing times. Her cage is 60 x 60 x 90 cm, has two dowel perches, one plastic toy, and is in the lobby. Staff want to buy a larger cage ($300, most of the budget) versus spend on foraging toys, perches, and a screen. A volunteer has been hand-feeding Juno when she screams.
1. Prioritize the welfare problems and explain how you would allocate the $400, with reasoning.

Rank the problems by likely impact on welfare:
- Feather damage (plucking) - a serious welfare indicator, often multifactorial: social isolation, lack of control, insufficient foraging opportunity, disrupted sleep, and possibly medical causes (skin, thyroid, nutritional). A veterinary assessment is the first step and is not optional; enrichment cannot fix an underlying medical cause.
- Pacing at opening and closing - a stereotypic behavior tied to predictable events (staff arrival and departure). This points to anticipation and arousal rather than space per se.
- Barren environment - one plastic toy, two dowels, lobby placement (constant unpredictable traffic, poor sleep).
- Screaming reinforced by hand-feeding - an operant problem layered on the welfare problems.
Allocation reasoning: a $300 cage consumes 75% of the budget and addresses only one variable, while the pacing and plucking are more consistent with social and foraging deficits than with cage dimensions alone. A better split: ~$120 on destructible foraging and puzzle toys rotated weekly; ~$80 on natural-variety perches (different diameters and textures) to address foot health and give more usable space; ~$60 on a visual screen or move to a quieter area (cost is mostly staff time); ~$60 reserve for a veterinary consult or feather/skin assessment; remainder on food-based foraging. The larger cage is a good long-term goal - fundraise for it separately rather than spending the whole month's budget.
2. Write the behavior plan for the screaming and pacing, including how staff should respond and how you would know it is working.

Screaming. The volunteer's hand-feeding is positive reinforcement on a variable schedule - the strongest schedule for maintaining a behavior. Stop feeding during screaming. Instead, feed a high-value item (a nut or piece of produce) when Juno is quiet, delivered on a predictable schedule at first (e.g., every staff pass at :00 and :30), then thinned. Give Juno a foraging toy at the times screaming peaks so the behavior is incompatible. Brief, calm social contact when she is quiet is fine and should be scheduled, not contingent on screaming.
Pacing. The pacing clusters at opening and closing, so it is likely anticipatory. Reduce the abruptness of transitions: cover the cage 30 minutes before closing, uncover gradually at opening, and give a foraging toy before staff leave so the last event is a positive, engaging one. Do not punish pacing - it is a welfare signal, and interruption without an alternative increases frustration.
Environment. Rotate toys weekly, add foraging opportunities, provide a quiet sleep period of 10-12 hours with a cover, and move the cage out of the lobby if at all possible. Increase out-of-cage time with staff if Juno is safe to handle.
Measurement. Record screaming in 10-minute blocks for 3 days as a baseline, then daily. Record pacing bouts (start, duration) at opening and closing. Record feather score weekly using a simple body-region checklist. Success at four weeks = at least 30% reduction in screaming and shorter pacing bouts, with no new feather damage. If plucking worsens despite compliance, the veterinary assessment takes priority - chronic plucking is often not resolved by enrichment alone, and the plan should not promise a cure.
