CASA0029 Interactive Visualisation
Understanding how migratory birds move through a changing city.
Every year, seasonal bird movements reveal hidden ecological rhythms across London's urban landscape.
Overview · Why London
London combines dense built form, fragmented green infrastructure and major migratory pathways. This makes it a useful urban laboratory for asking where bird activity concentrates, when it peaks, and which environments support it.
Overview · Species Selection
The selected three species represent different temporal patterns, providing a basis for further analysis.
Flight Patterns · Seasonal Rhythm
Migratory birds do not appear randomly. Their records follow distinct seasonal rhythms, reflecting migration timing and ecological adaptation.
Flight Patterns · Migration Peaks
Use the seasonal cards to reveal how arrival, peak activity and transition periods create different observation windows.
Flight Patterns · Spatial Hotspots
Use species and season controls to explore how hotspots shift across London at MSOA level.
A long-distance migrant often associated with open landscapes and riversides.
Early hotspots emerge in suburban and riverside areas.
Interactive Module 2 | Urban Conditions
Do high-record bird observation areas tend to sit near parks, water corridors, or dense urban settings? Use the map first: filter hotspots, follow the short story route, then compare two MSOAs.
Bird Hotspot Habitat Map
Filter, compare, and inspect cumulative 2021-2025 bird records by MSOA.
Urban Habitat · Environmental Profiles
Green cover, water proximity and building density help explain why some areas act as repeated bird observation clusters while others remain weaker.
Urban Habitat · Compare Areas
Select two habitat profile types to compare records, green cover, water cover and built context.
Attention Zones · BHP Index
The Bird Habitat Pressure Index (BHP) is a composite interpretation layer. It balances supportive ecological conditions against urban pressure, helping identify where bird activity is already well supported and where restoration or mitigation should be prioritised.
Higher scores indicate stronger habitat potential; lower scores indicate areas where disturbance and environmental stress may reduce ecological suitability.
The formula keeps the logic transparent: habitat quality and connectivity increase BHP, while human disturbance and light pollution reduce it.
Represents local habitat support, including greener or more ecologically favourable conditions.
Captures whether the area can function as part of a wider ecological movement network.
Approximates anthropogenic load such as dense built fabric and direct urban disturbance.
Represents artificial night-time light exposure that can disturb orientation, feeding and nesting behaviour.
Attention Zones · Interactive Map
This map converts the BHP score into planning categories. Click an MSOA to inspect its BHP score, bird records, ecological determinants and suggested planning action.
Attention Zones · 3D Morphology
Click an MSOA polygon on the left. The model rebuilds the selected area as an urban-form profile: warm towers show disturbance and night-light pressure, while blue-green terraces show habitat quality and ecological connectivity.
Attention Zones · Planning Logic
The BHP classes are not just map colours. They translate bird records and urban conditions into different levels of intervention, from conservation to retrofit.
Keep mature tree cover, reduce lighting spill, protect nesting opportunities and avoid fragmentation around the strongest BHP areas.
Bird records + habitat quality + connectivity + pressure indicators
MSOA screening first, then site-level design and policy review
Supports urban greening, biodiversity net gain, blue-green infrastructure and light-sensitive design
Future · Planning the Flyway
The next step is to use the visualisation as a decision-support layer: where to protect, where to connect, and where to retrofit bird-sensitive urban space.
Use rivers, reservoirs, parks and wooded edges as a connected movement system. BHP hotspots can identify where corridor continuity should be strengthened.
Future · Limitations
Observation records are influenced by survey effort, accessibility and reporting bias. The maps should be read as exploratory evidence for spatial patterns rather than complete measures of bird abundance.
Future · Team
Project members responsible for spatial analysis, interaction design and website integration.
