House Crow Nesting Preferences in Singapore Over Two Decades

Survey data from 60 nesting and non-nesting trees for the invasive Indian house crow (Corvus splendens) in Singapore. The dataset includes LiDAR-based measurements of terminal branch angles and tracks long-term behavioral shifts in nesting preferences. It was authored by Yong Xu Leong and last updated on 2026-05-25.

Use Cases

• Modeling crow nesting site selection based on tree height and branch angle measurements.
• Analyzing the influence of proximity to human infrastructure on invasive species nesting.
• Tracking long-term behavioral shifts in urban wildlife in response to landscape changes.
• Informing urban planting strategies to discourage communal nesting of invasive birds.

Strengths

• Includes novel LiDAR-based measurements of terminal branch angles.
• Compares current data with historical findings to track long-term behavioral shifts.
• Surveyed 60 nesting and non-nesting trees.
• Released under a CC-BY-4.0 license for open use.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is relatively small at 4.7 MB, which may constrain complex modeling.
