The Nestling Growth App is a web-based tool designed for ornithologists, ecologists, and researchers working on nestling development. It allows users to visualize and model growth metrics such as weight, wing, and tarsus length using classic biological growth functions:

• Von Bertalanffy
• Extreme Value Function (EVF)

It includes language support (English, Spanish, Portuguese) and dynamic content based on user selection.

✨ Features

✔ Dynamically select variables (e.g., weight, wing, tarsus)
✔ Automatically fits multiple growth models
✔ Exports results (tables and graphs) as CSV and PNG
✔ Interactive interface with tabs for Weight and Wing & Tarsus
✔ Multilingual: 🇬🇧 English, 🇪🇸 Español, 🇵🇹 Português

📥 Input Format

Your CSV must include:

• A column for day (e.g., Day, Age, Día, etc.)
• At least one of the following: Weight, Wing, or Tarsus

📤 Output
