“…In addition, the number of detections during playback surveys was more than twice that of visual/aural surveys, and the use of playback allowed us to detect species missed during visual/aural surveys. Thus, our results indicate that the response of Asian woodpeckers to call playback was similar to that of woodpeckers in North America (Resources Inventory Committee 1999), Europe (Michalczuk and Michalczuk 2006), and South America (Vergara and Schlatter 2004). Most responses (83%) by woodpeckers in our study occurred within 1 min, suggesting that using playback to survey Asian woodpeckers results in both rapid and accurate detections.…”

Tropical forests have exceptional woodpecker diversity, but little is known about the abundance and diversity of woodpeckers in the Indian subcontinent, particularly for the Shorea robusta‐dominated moist deciduous forests of northern India. Our objective was to compare the number of woodpecker species and number of individuals detected using playback surveys and visual/aural transect surveys at five sites. Each site was surveyed 5–6 times along a 2000‐m transect, with woodpeckers detected using two methods: (1) visual and aural cues, and (2) playing back calls of 13 species at 400‐m intervals. Both methods involved similar effort per survey (100–110 min). During surveys, we detected 11 species of woodpeckers. More species and more than twice as many individuals were detected during playback surveys than during visual/aural surveys. In addition, species accumulation curves showed that we detected the species known to be present based on previous work faster with playback surveys than with visual/aural surveys at four of the five sites. During field trials, 97% of targeted individuals (N= 269) of 12 species responded to playback, and 83% of the responses occurred within 1 min of broadcast. The number of species of woodpeckers in our study area (11 species) was typical for a structurally diverse, tropical/subtropical moist broad‐leaved forest. Our results demonstrate that playback surveys are more efficient and accurate than visual/aural surveys, and that playback surveys can be useful for assessing and monitoring woodpecker diversity in tropical forests.

“…Such a dependency can also be discerned in the Syrian Woodpecker population. In the study area, where the species reaches a density of approximately 14-20 pairs/ 10 km 2 in optimal habitats (Michalczuk and Michalczuk 2006a), females lay more eggs than in Israel, where the population density reaches over 40 pairs/10 km 2 (Shirihai 1996). In that region, the Syrian woodpecker clutch size is the smallest, ranging from three to five eggs (Barnea 1982;Shirihai 1996;Al-Safadi 2004).…”

“…The study area (305 km 2 ) was inhabited by 30 breeding Syrian Woodpecker pairs in 2003, but this number had increased to 50 by 2006 (Michalczuk and Michalczuk 2006a; own observations). The area is located in the southeastern part of Poland (50°28 0 N, 23°40 0 E) and is characterized by gentle hills that are 195-263 m above sea level (Kondracki 2000).…”

Syrian Woodpecker nests were studied in a 305-km 2 area of the agricultural landscape in SE Poland. The median egg-laying date was found to be 12 May and the median fledging date was 20 June (the earliest laying date was April 24 and the latest fledging date was July 25). Females laid from two to seven eggs (median 5.0 eggs, n = 56). An average of 4.4 young hatched per nest (SD = 1.18, median 5, maximum 6, n = 41) after 9-13 days of incubation (median 10 days, n = 37). Two to six nestlings left successful nests (median 4, n = 37) after 24-30 days (median 27, n = 36), with a mean of 2.8 (SD = 2.24, median 3, n = 56) young fledging per nest. The main reason for the loss of young observed in 31 % of the Syrian Woodpecker broods was nest parasitism by starlings. These results suggest that the process and dynamics of the range expansion of the Syrian Woodpecker are influenced by a higher reproductive output of Syrian Woodpeckers at the extremities of its range as compared to that of the rest of the Syrian Woodpecker population. April; spätestes Ausflugdatum 25. Juli). Die Weibchen legten zwischen 2 und 7 Eiern (Median 5 Eier, n = 56). Nach 9-13 Tagen Brüten (Median 10 Tage, n = 37) schlüpften bis zu sechs Jungvögel, mit einem Durchschnitt von 4.4 Jungen pro Nest (SD = 1.18, Median 5, n = 41). Nach 24-30 Tagen (Median 27, n = 36) im Nest, flogen 2 bis 6 Jungtiere aus dem Nest einer erfolgreichen Brut aus (Median 4, n = 37), mit einem Durchschnitt von 2.8 (SD = 2.24, Median 3, n = 56) insgesamt. Der Hauptgrund für Brutverluste, der bei 31 % der Bruten des Blutspechts gefunden wurde, war Nestparasitismus durch Stare. Die Ergebnisse deuten darauf hin, dass der Prozess und die Dynamik der Ausbreitung des Blutspechts beeinflusst wird durch eine höhere Reproduktionsrate der Population an den äußersten Rändern des Verbreitungsgebiets im Vergleich zur Population im Zentrum.

“…Woodpeckers can be challenging to detect or locate (Kosinski & Kempa, ), as they are often secretive (Michalczuk & Michalczuk, ), quiet for long periods, overlooked among large trees that they inhabit (Allen & Kellogg, ), occupying wooded habitats with low visibility, cryptic (Kumar & Singh, ), or wary of humans (Conner, Jones, & Jones, ). Although some species or individuals may be more easily detectable by their drums or vocalizations (e.g., Drever, Aitken, Norris, & Martin, ; Vergara et al, ), not all woodpeckers express the same easily detectable behaviors or only may be more easily detectable seasonally.…”

Woodpeckers can be difficult to detect, as they are often cryptic, secretive, occurring in low densities, and wary of humans. Several methods exist to detect woodpeckers (e.g., playback surveys, passive point counts), yet no research has established which technique best detects these elusive picids. Thus, we designed an experiment to determine which of three methods best results in a detection of Magellanic Woodpeckers (Campephilus magellanicus), and if weather variables influence detection probability. Mostly during austral summers 2015–2017, we (a) used a drumming device to simulate a double‐knock (i.e., territorial acoustical signal), (b) broadcasted a territorial call, and (c) passively listened (control) for Magellanic Woodpeckers. We conducted our experiment on Navarino Island, Chile, where the Magellanic Woodpecker is the sole picid. The drumming device most effectively influenced the likelihood of a woodpecker detection. The odds of a woodpecker responding to a double‐knock were 2.14 times more likely than responding to either a call or control. Moreover, the odds of a woodpecker detection decreased by 42% as wind increased by one category and decreased by 40% for every additional month (i.e., October–March), which was expected because woodpeckers become less territorial as the breeding season progresses. As Campephilus woodpeckers communicate via drums or double‐knocks, using a drumming device likely will be an effective technique to detect not only Magellanic Woodpeckers, but other woodpeckers within the Campephilus genus in Central and South America.
