Introduction:
Onceaspeciesthatthrivedinbothurbanandruralsettings,housesparrows(Passer domesticus)haveexperiencedsharp population declines in recent years. Urbanization, climate change, and habitat loss are among the primary causes of this reduction. While traditional ecological studies rely on field surveys and observational data, these approaches often lack scalability and predictive accuracy. Machine learning offers a data-driven approach to analyzing large-scale avian population data; however, research in this area remains limited, with most studies focusing on direct field observations ratherthanpredictivemodelling.
Several key challenges exist in house sparrow population analysis. There is a limited application of artificial intelligence andmachinelearningmodelsforstudyinglong-termpopulationdynamics.Additionally,thelackofintegrationoftemporal trends makes it difficult to accurately forecast future sparrow populations. Data-driven methods for classifying habitatbased population fluctuations are underutilized, and there is a need for a comprehensive examination of environmental factorsinfluencingsparrowdistribution.
To address these gaps, this study applies machine learning techniques, including Random Forest for habitat-based classification,ARIMAfortime-seriesforecasting,andK-Meansclusteringtoidentifyenvironmentalinfluencesonsparrow populations.Thedataset,coveringtheyears2015–2025,enablesanin-depthanalysisofpopulationtrendsacrossdifferent geographicalandtemporalscales.
The primary objectives of this research are: developing a predictive model using ARIMA to anticipate future sparrow population trends; classifying populations based on habitat conditions using machine learning algorithms, and utilizing

Literature Review:

Numerous contributory variables have been discovered by researchers, including increased pesticideuse,habitatdestruction,communicationtowerelectromagneticradiation,andfasturbanization.(1)Sharmaetal. highlight how sparrow populations have been gradually declining as a result of modern construction designs and infrastructurethatdrasticallylimitbreedingoptions.Likewise,Shansazetal.(2)drawattentiontothedetrimentaleffects that chemical exposure and environmental pollution have had on sparrow populations in both urban and rural settings.modelingtocomprehendsparrowpopulationdynamics.
Accordingtorecentdevelopmentsinecologicaldataanalysis,combiningclassificationmodels(RandomForest),clustering (K-Means),andtime-seriesforecasting(ARIMA)canprovidegreaterinsightsintothedynamicsofspeciespopulations.In order to categorize habitat types and forecast future population changes, previous research has mostly depended on mapping geographic distributions without utilizing unsupervised learning approaches. By using geospatial analysis tools oneBirdobservationaldata,thisstudyseekstoclosethisgapandprovideamorethoroughanddata-drivenapproachto housesparrowconservation.
Methodology:
4.1
Three main analytical techniques are used in this work to look at house sparrow population trends. First, historical sparrow population data is analyzed and future trends are predicted by time series forecasting utilizing the ARIMA (AutoRegressive Integrated Moving Average) model. This facilitates the identification of possible decline phases and enablesagreaterknowledgeofpopulationvariationsthroughouttime.
Second, K-Means clustering is used for habitat clustering through geospatial analysis. This method groups sparrow habitats according to their geographic locations and environmental characteristics. This method facilitates the identificationofareaswithhighandlowpopulationdensities,allowingformorefocusedconservationefforts.
Finally, the Random Forest classification model is used to classify species based on observational data. This aids in the analysis of sparrow sightings and the identification of important environmental variables affecting population dispersal. Thisstudyoffersathoroughanddata-drivenecologicalanalysisthatgoesbeyondconventionalconservationassessments bycombiningthesemethodologies.

Pandas and NumPy are utilizedforfeaturetransformation,missingvaluemanagement,andeffectivedatasetstructuring.Visualrepresentationsof populationtrends,clusterdistribution,andforecastingoutcomesareproducedwiththehelpofMatplotlibandSeaborn.
For machine learning applications, Scikit-learn is applied for classification and clustering, while Statsmodels is used for ARIMA-based time series forecasting.

Several computational models are used in the study to better understand the dynamics of sparrow populations. Timeseries data is analyzed using ARIMA forecasting, which helps detect possible decline periods and forecast future populationpatterns.
K-means clustering is used for spatial clustering, which groups sparrow habitats according to their geographic locations. Thismakesitpossibletodivideareasintohigh-density andlow-densityzones,whichiscrucial forcreatingconservation plansthatwork.
Furthermore, based on geographical and environmental characteristics, observation sites are classified using Random Forest classification into high, moderate, or low sparrow presence. This aids in identifying the areas best suited for sparrowresidenceandconservationinitiatives.
Root Mean Squared Error (RMSE) for ARIMA forecasting, inertia for K-Means clustering, and classification accuracy for Random Forest models are used to assess model performance. These measures guarantee that the models generate accurateandcomprehensibleoutcomes.
A thorough grasp of house sparrow population patterns is made possible by this study's integration of time-series forecasting, clustering, and classification into a single analytical framework. ARIMA forecasting enables academics to predictpossiblereductionsinvariousplacesbyofferinginsightsintolong-termpopulationtrends.
By graphically depicting high-density and low-density sparrow habitats on satellite maps, K-Means clustering improves geospatial analysis. This method aids in the development of focused conservation strategies in addition to identifying importanthabitats.
Additionally, classification algorithms make it possible to pinpoint the main environmental elements affecting sparrow populations.

SpeciesClassification&EnvironmentalInfluence(RandomForestModel)
The Random Forest classifier was applied to analyze environmental factors influencing sparrow population distribution. The model achieved an accuracy of 89.6%, demonstrating strong predictive performance. However, feature importance analysisrevealedthatgeospatialcoordinates(latitudeandlongitude)hadnegligibleinfluence,withbothshowingascore of0.0.
This suggests that other unaccounted ecological factors such as vegetation cover, food availability, noise pollution, and air quality may play a more significant role in determining sparrow populations. Future studies should consider integrating additional environmental variables, such as temperature, noise levels, and air pollution indices, to enhance classificationaccuracy.

According to the ARIMA forecast, the study shows a slow fall in house sparrow populations, especially in metropolitan areas. Even though there are occasional variations, the long-term trend points to a steady decline, highlighting the necessityofconservationmeasures.
Withlow-densityclustersinheavilyurbanizedareasandhigh-densityclustersinruralandsemi-urbanareas,theK-Means clustering analysis clearly shows variances in population density. This demonstrates how urbanization, pollution, and habitatdestructionhaveadetrimentaleffectonsparrownumbers.
Even with its 89.6% accuracy, the Random Forest classification algorithm shows that sparrow population predictions cannotbemadeonlybasedongeospatialcriteria.Thisimpliesthatforimprovedpredictionaccuracy,otherenvironmental factorsincludingfoodavailability,vegetationcover,andairpollutionlevelsshouldbeincluded.
