Total Captures: 459
Captures by Day
Fig. 1. The number of captures recorded each day over the selected period.
Days are shown in chronological order.
Captures by Species
Fig. 2. Species are list in taxonomic order
and labeled by their 4-letter alpha codes. Click on each bar to see the species
name rather than the alpha code
Captures by Sexes
Fig. 3. Sex determinations are made based on a variety of physical
characteristics. However, not all birds can be confidently sexed due to limitations
such as age, lack of sexually dimorphic features, or non-breeding season conditions,
leading to some being classified as 'Unknown'. Adult males often display more
distinctive traits, making their identification more straightforward. Caution
should be exercised when interpreting the relative proportions of males to females,
as apparent discrepancies may arise from these sexing challenges.
Captures by Age
Fig. 4. Birds aged using the calendar-year
methodology, highlighting the most frequently encountered age classes. 'Local'
refers to young birds not yet capable of sustained flight, while 'Hatching Year'
denotes birds known to have hatched this year. 'Second Year'
and 'After Second Year' indicate birds in their second calendar year and those older,
respectively. 'After Hatching Year' serves as a broad category for adults whose exact
year of hatching is unknown, emphasizing the bird's maturity without specific age detail.
Figure 5 - Captures per Net
Fig. 5. Capture distribution across nets at a
MAPS station, reflecting the total count of birds captured per net. Nets are employed
based on a standardized protocol to ensure optimal coverage and efficient capture
rates, placed in strategic locations to maximize the capture of breeding adults and
dispersing young. Each bar represents the cumulative captures for a specific net,
providing insights into the spatial distribution of captures and potential netting
hotspots within the study area.
Figure 6 - Captures by Type
Fig. 6. Distribution of three principal
categories of bird captures: New, Recaptured, and Unbanded. New captures refer to
birds that are banded for the first time. Recaptures involve birds previously banded,
which may include returns (birds banded in the same place on earlier occasions),
repeats (additional captures within the same year), and foreign recaptures (birds
initially banded at a different location). Unbanded birds include those who escaped
before being banded or not suitable for banding, such as escapees or species
not authorized for banding
