Denver Zoo’s Tamandua Winnie Is Pregnant, First Birth in Over a Decade Expected Early 2026

The pregnancy stems from an AZA breeding recommendation pairing Winnie with Nashville transfer Santiago.

Overview

  • Zoo staff verified the pregnancy with an ultrasound in October and plan to continue routine scans.
  • The birth is anticipated in early 2026, and southern tamanduas typically deliver a single pup.
  • Winnie moved to Denver in 2018 under a breeding program, and an earlier pairing with Laird was unsuccessful.
  • The father-to-be, Santiago, was transferred this year to support managed breeding objectives.
  • Winnie participates in voluntary healthcare, including injections and ultrasounds, and she continues enrichment walks during pregnancy.
