Alpha Code: BLJA
Spanish: Chara Azul
French: Geai bleu
Band Size: 2 ~ 3
NW Ohio Status: Present all year
Total Banded in Spring: 1,465
Average Banded in Spring: 49
Total Banded in Fall: 145
Average Banded in Fall: 5
Song: variety of calls, imitations, and harsh cries including jay-jay!
Description: Blue above with gray-white face and underparts. Black bar in front of eye and black border around face leading into crest. Brilliant blue wings and tail with black bars and white tips. Male and female alike throughout the year.
Spring Migration Timing: Small flocks begin moving in late April with larger flocks and the bulk of total birds occurring May 1-11.
Fall Migration Timing: Encountered in low numbers throughout fall, with spikes of activity occurring in mid- and late September, possibly suggesting migrant activity.
Migration Habitat: Common throughout a variety of forested habitats and adjacent clearings including deciduous forests, urban parks, and backyards.
Notes: Migrant BLJA in spring tend to remain high in the canopy. Combined with point count and observational data, thousands of individuals will pass overhead during spring (outside the range of capture) generally within a few hours.
Alpha Code: RBNU
Spanish: Sita Canadiense
French: Sittelle à poitrine rousse
Band Size: 0 ~ 1
NW Ohio Status: Migrant, Breeding-rare, Winter-irregular
Total Banded in Spring: 179
Average Banded in Spring: 6
Total Banded in Fall: 356
Average Banded in Fall: 12
Song: fast, nasally, high-pitched yank-yank-yank-yank
Description: Slate-blue above with orangish underparts. Striped face with white eyebrow, black eyeline, and white moustachial area. Male with bluer back and rich orange underparts; black crown. Female with grayer back and pale orange underparts; matte, dark gray crown.
Spring Migration Timing: Sporadic and dependent on distance of winter dispersal and movements in late winter. Peak movements of RBNU still migrating in spring tend to occur in late April and early May, but can extend into mid-May.
Fall Migration Timing: Dependent on northern cone production and pre-winter dispersal, but can extend from late August into November, with peak movements occurring September 23 through October 7.
Migration Habitat: Variety of forest types (especially those with conifers) but can also appear at backyard feeders.
Notes: Shows years of irruptive migration when cone production in northern areas is low. While RBNU can typically be found to some degree every year in fall through spring, irruptive years produce the highest numbers of birds in fall and in the following spring.
